The function of main cards on Keymile

SUPX3 IPSX2 COGE1

The SUPX3 unit have 32 PSTN user ports.

The IPSX2 unit converts TDM based voice traffic into IP packetsIt can serve up to 608 PSTN or 304 ISDN-BA subcribers

The COGE1 unit represents the core control unit

Bring up Keymile GW

3, Datafill on CoreLogin (OSSGATE) to create the endpoints, then we get the its LENsCreat new DN (Directory Number) on the LENs created

1, Setup the parameters needed on Keymile side as GW name, IP of GW and IP of GWC where the Keymile is pointed to.

2, Associate to GWCLog in CMT interface to associate Keymile GW to GWC

Test plan 1. Document goalThe goal of test plan provide test coverage for function of Line Gateway. 2. Resource requirements

# Maintenance

1, Verify Keymile line call attempt after multi restart GW

2, Verify Keymile line call attempt after GWC warm/cold swact

Somes Functions are covered in testplan :

# Feature

1, Call Forwarding Unconditional(CFU)CFU feature allows the system to forward all

calls to a predetermined destination number unconditionally.

Use SERVORD to add the CFU to the line B:ADO $ DN(B) CFU N $ Y Y

2, Call Forward on Busy (CFB)If CFB feature is in effect, all incoming calls are

rerouted immediately to an alternative number when the subscriber line is found to be busy.

Use SERVORD to add the CFB to Line B: ADO $ DN(B) CFB P $ Y Y

3, Call Pickup (CPU)CPU feature allows a station to answer calls

incoming to another station in a same pickup group. Use SERVORD to add option CPU to line B and C:

EST $ CPU LEN(B) LEN(C) $ Y Y

4, Simultaneous Ring (SIMRING)SimRing feature allows simultaneous incoming

call notification for the members of a user-defined SimRing group. A SimRing group contains a single pilot directory number (PDN) and up to four non-pilot member DNs (NPMDN). Use command EST in SERVORD to assign SIMRING to an existing line, and add member of SIMRING:

EST $ SIMRING DN(B) DN(C) $ ACT Y 123
