17.1 Background Knowledge

17.1.1 Overview to Network Management Instructions

To ensure the quality of service (QoS) of the telecommunications networks, carriers

need to design the network capacity and inter-node routes reasonably and manage

the nodes in the network efficiently. In this way, traffic can be restricted in the case of

overload to reduce call loss and guarantee the reliable and efficient operation of the

network.

Network Management (NM) is implemented by the Network Management Center

(NMC) to control, schedule, and measure the nodes, such as switching equipment

and transmission equipment, in the telecommunications network. Controlling outgoing

calls of nodes and scheduling routes is the core NM function.

To achieve NM, the nodes in the network should be able to receive and carry out the

instructions from the NMC. The SoftX3000 offers abundant NM instruction sets, which

facilitates the carriers to control and schedule the SoftX3000.

17.1.2 Purposes of Network Management Instructions

The NM instruction sets of the SoftX3000 include originating destination code control,

outgoing destination code control, call gap control, circuit orient control, circuit reject

control, direct route control, alternative route cancellation control, temporary

alternative route control, skip sub-route control, special record notification control,

trunk reserved control, and Hard To Reach (HTR) control.

The purposes of these NM instructions are described as follows.

I. Originating destination code control

It means that the switch prohibits the calls to designated destination codes from

designated incoming trunks or callers by a certain percentage.

Designated incoming trunks: Incoming trunk groups configured with a specific

NM source code.

Designated callers: Callers with specific caller category, country code, area

code, office number, or subscriber number.

第6章 1



Management Data

第10 章 Designated destination codes: Specific country code, area code, office number,

subscriber number, or special service number.

Generally, whether an outgoing call is barred depends on the caller category, and

whether an incoming or forwarded call is barred depends on the incoming circuit

group type. The system first prohibits the calls from some common callers or trunks.

After all common calls are barred, the system prohibits the calls from priority callers or

trunks. Hierarchical barring of common calls is adopted, and 25% of total common

calls are barred for each level. There is no hierarchical barring of priority calls.

II. Outgoing destination code control

It means that the switch prohibits the calls to designated destination codes from

occupying designated outgoing trunks by a certain percentage.

Designated destination codes: Specific country code, area code, office number,


Designated outgoing trunks: Outgoing trunk groups configured with a specific

NM source code.

III. Call gap control

It means that the switch restricts the maximum number of call attempts to designated

destination codes from designated callers during a certain interval.

That is, if the call attempts of designated callers to designated destination codes

during the designated interval exceed the number of call attempts defined here, the

system automatically starts the call barring function to prohibit these callers from

dialing the destination codes. The call barring will not end until the system cancels it

automatically or you cancel it with DEA NM.

Designated callers: Callers with specific caller category.



IV. Circuit orient control

It means that the switch changes bi-directional trunk circuits to incoming trunk circuits

according to the designated quantity or by a certain percentage.

V. Circuit reject control

It means that the switch suspends bi-directional and/or unidirectional trunk circuits

according to the designated quantity or by a certain percentage.

第6章 2



Management Data

第10 章VI. Direct route control

It means that the switch restricts the direct traffic of the designated sub-route by a

certain percentage. It has two control modes:

Incoming prohibited (DRT): The switch prohibits the direct traffic to the

designated sub-route by a certain percentage. The overflown traffic is routed to

the other sub-routes.

Overflow prohibited(DRF): The switch prohibits the direct traffic overflown from

the designated sub-route by a certain percentage. The overflown traffic is

canceled directly.

VII. Alternative route cancellation control

It means that the switch restricts the alternative traffic of the designated sub-route by

a certain percentage.

Incoming prohibited (ART): The switch prohibits the alternative traffic to the


the other sub-routes. For example, a local network is networked as shown in

Figure 17-1. For Office A, Sub-route A to B is an alternative sub-route for C to B,

D to B, and E to B. If the direct traffic on Sub-route A to B is too heavy during a

period of time, you can prohibit the alternative traffic of C to B, D to B, and E to B

from entering Sub-route A to B with this NM instruction in order to ensure the

direct traffic on A to B.

第21章 Figure 17-1 Restricting alternative traffic (ART)

Overflow prohibited (ARF): The switch prohibits the alternative traffic overflown

from the designated sub-route by a certain percentage. The overflown traffic is

canceled directly. For example, a local network is networked as shown in Figure

17-2For Office A, Sub-route A to B is an alternative sub-route for C to B. If both

第6章 3



Management Data

第10 章the direct and alternative traffic on Sub-route A to B is too heavy during a period

of time, you can prohibit the overflown alternative traffic of C to B from entering

Sub-route A to B again with this NM instruction in order to ensure the direct

traffic on A to B.

第22章 Figure 17-2 Restricting alternative traffic overflow (ARF)

VIII. Temporary alternative route control

It means that the switch allows the calls from designated callers or incoming trunks to

designated destination codes to use the designated alternative sub-routes temporarily

by a certain percentage.


NM source code.





IX. Skip sub-route control

It means that the switch allows the calls from designated callers or incoming trunks to

designated destination codes to skip the designated sub-route by a certain

percentage. The designated sub-route to be skipped can carry either direct traffic or

alternative traffic.

For example, a local network is networked as shown in Figure 17-3. For Office A,

Sub-routes A to B and A to D are alternative sub-routes for C to E. In normal cases,

Office A first selects Sub-route A to B (direct sub-route) and selects Sub-route A to D

(alternative sub-route) in the case of traffic overflow when transferring the calls

originated by Office C to Office E. If the direct traffic from Office A on Sub-route A to B

第6章 4



Management Data

第10 章is too heavy during a period of time, you can prohibit the direct transfer traffic from

entering Sub-route A to B with this NM instruction in order to ensure the direct

outgoing traffic on A to B. That is, Office A can skip Sub-route A to B and directly

selects Sub-route A to D when transferring the calls originated by Office C to Office E.

Figure 17-3 Skip sub-route control

X. Special record notification control

It means that the switch can play the special announcement for the calls from

designated callers or incoming trunks to designated destination codes to notify the

callers or operators of delaying the calls.


NM source code.





XI. Trunk reserved control

It means that the switch dynamically adjusts the traffic of outgoing trunks according to

the availability of the designated outgoing trunk group. This NM instruction needs the

cooperation of the parameters “Idle circuits for weak call restriction” and “Idle circuits

for forced call restriction” of trunk groups. The options are

No call restriction: If the actual number of idle circuits of the designated trunk

group = “Idle circuits for weak call restriction”, this NM instruction is invalid.

Weak call restriction: If “Idle circuits for forced call restriction = the actual number

of idle circuits of the designated trunk group < “Idle circuits for weak call

restriction”, the system restricts the calls by “Weak restriction percent”.

第6章 5



Management Data

第10 章 Forced call restriction: If the actual number of idle circuits of the designated trunk

group < “Idle circuits for forced call restriction”, that is, the trunk group is to be

congested, the system restricts the calls by “Forced restriction percent”.

XII. HTR control

It means that the switch can automatically prohibit the calls from designated callers or

incoming trunks to designated destination codes by a certain percentage if these

destination codes are not reachable to some extent. When a destination code is

judged as “reachable”, the system cancels call restriction automatically.


NM source code.





For example, if an incoming trunk makes more then 100 call attempts to a prefix 369

within five minutes and the answer attempt ratio is less than 10%, it means that the

office 369 is unreachable, and the switch will automatically restrict the calls to the

prefix 369 by a certain percentage.

ranging from 0 to 65535. Generally, it is not set but allocated by the system

automatically.



[Weak restriction percent], [Forced restriction percent]

They define the call restriction percentage when the system starts the trunk reserved

control in order to dynamically adjust outgoing traffic. This NM instruction needs the

cooperation of the parameters “Idle circuits for weak call restriction” and “Idle circuits

for forced call restriction” of trunk groups. The options are

No call restriction: If the actual number of idle circuits of the designated trunk

group = “Idle circuits for weak call restriction”, this NM instruction is invalid.

第10 章 Weak call restriction: When “Idle circuits for forced call restriction = the actual

number of idle circuits of the designated trunk group < “Idle circuits for weak call

restriction”, the system restricts the calls by “Weak restriction percent”.

Forced call restriction: If the actual number of idle circuits of the designated trunk

group < “Idle circuits for forced call restriction”, that is, the trunk group is to be

congested, the system restricts the calls by “Forced restriction percent”.

[Call type]

It defines the type of calls to be restricted by the NMS. Set this parameter by the










[Caller category]




[Service type]

It specifies the type of the routing service for which call restriction is to be

implemented. The options are alternative service, direct service, and direct and

alternative service.

[Outgoing trunk NM source code]

It specifies the outgoing trunk group occupied by the to-be-prohibited calls to the

designated destination code. Its value ranges from 0 to 65534. By default, it is

“65534”, which is the wildcard character and indicates all outgoing trunk groups.

[Control type]

It specifies the control mode used by the system to prohibit the calls to the designated

destination codes to occupy the outgoing trunk groups. The options are

Cancel: The system prohibits the alternative traffic overflown from the designated

sub-route by a certain percentage. The overflown traffic is cancelled directly.

Skip: The system restricts the alternative traffic to the designated sub-route by a

certain percentage. The overflown traffic is routed to the other sub-routes.

第10 章17.3 HTR Control Instructions

17.3.1 Adding HTR Description

I. Related commands

Command Function

ADD HTRDESC To add HTR description

RMV HTRDESC To remove HTR description

MOD HTRDESC To modify HTR description

LST HTRDESC To list HTR description

II. Notes of configuration

HTR control means that the switch can automatically prohibit the calls from

designated callers or incoming trunks to designated destination codes by a certain

percentage if these destination codes are not reachable to some extent. When a

destination code is judged as “reachable”, the system cancels call restriction

automatically.

When you add HTR control description, the system creates automatically a traffic

measurement task of HTR control for analyzing the measurement results reported by

all FCCUs/FCSUs every five minutes.

If the measurement results meet the conditions for starting HTR control

automatically, that is, “Call attempts to prohibited destination codes” is equal to

“Call attempts in HTR description table” and “Percentage of answered attempts

to prohibited destination codes” is less than “Percentage of answered attempts in

HTR description table—Percentage of delayed attempts”, the BAM sends to the

host the originating destination code control instruction automatically.

If the measurement results meet the conditions for stopping HTR control

automatically, that is, ”Call attempts to prohibited destination codes” is less than

“Call attempts in HTR description table” and “Percentage of answered attempts

to prohibited destination codes” is bigger than or equal to “Percentage of

answered attempts in HTR description table—Percentage of delayed attempts”,

the BAM stops HTR control and deletes the originating destination code control

instruction automatically.

Management Data

第10 章After setting HTR description, use LST NM to query whether HTR control is started. If

the originating destination code control instruction is set due to “HTR generation”, it

indicates that HTR control has been started.

III. Parameter description

[Local DN set]

It specifies the local DN set of the destination code for which HTR control is needed.

This parameter must be defined in the ADD LDNSET command before being

referenced here.

[Destination code]

It specifies the destination code for which HTR control is needed, which can be a

country code, area code, office number, subscriber number, or special service

number. The system analyzes the destination code according to maximum matching

principle.

[Call attempts in 5 minutes]

As one of the conditions for starting HTR control, this parameter specifies the number

of call attempts within five minutes in the HTR description table.

After you set the HTR description, the system starts to count the number of call

attempts within the next five minutes. Five minutes later, the system judges whether

HTR control needs be started. For example, if you set HTR description at 12:22 in a

certain day, the system starts traffic measurement at 12:25. At 12:30, the system

judges whether HTR control needs be started according to the traffic measurement

result within the five minutes.

[Percentage of answered attempts]

As one of the conditions for starting HTR control, this parameter specifies the ratio of

answer attempts to call attempts in the HTR description table. Its value ranges from 1

to 100 in unit of %.

[Percentage of delayed attempts]

As one of the conditions for starting HTR control, this parameter specifies the delay

percentage of automatically starting or stopping HTR control in the HTR description

table. Its value ranges from 1 to 100 in unit of %.

[Percentage of restricted calls]

It specifies the percentage based on which the system restricts the calls, ranging from

1 to 100 in unit of %.

[Call type]

17.3.2 Setting HTR Switch

I. Related commands

Command Function

SET HTRSW To set HTR switch

LST HTRSW To list HTR switch


When you add HTR description, the system automatically creates and starts a traffic

measurement task of HTR control by default. To suspend the traffic measurement

task, use SET HTRSW to set the HTR switch to “OFF”.


[HTRSW]

When HTR control is started, this parameter is used to control the system to start or

stop a traffic measurement task of HTR control. By default, it is “On”.
