Installation Checklist

Ensure CCA is complete.

Download all the latest software.

Ensure the availability of Internet connectivity.

Gather the IP address, network mask, and DNS serverinformation from the Internet service provider.

Ensure the availability of PSTN access via either FXO, BRI, orT1/E1 PRI.

Installation Checklist (Cont.)

Place the UC520, CE520, and WLC526 units in a location thatallows for access to the front panel.

Ensure all units have access to power and remote connections.

Ensure the appropriate grounding wires and other electrical safetyissues have been addressed.

Ensure installation has been completed.

Verify the factory default VLAN, internal IP addresses, SSID, anddial plan to be used.

Implementation Process

7/28/2019 SMBEN20S07L02


Provisioning Sequence

Initial Setup

Verify pre-configured plug-and-play functionalities

Upgrade the system software if necessary

Provision Internet connection and DNS

Provision for off-network calls Verify working IP telephony

Expand wired network by adding CE520 devices

Enable WLAN using integrated AP (for 8 to 16-user models only)

Expand the WLAN:

Autonomous AP (AP-521)

WLAN Controllers (WLC-526)

Set additional configurations for the SBCS network

Provision VPN service for mobile workers and teleworkers

CCA

Launch CCA.

Create a community of SBCS devices.

Restart CCA and verify creation of community.

Verify UC520 device has the latest systemsoftware; if not, upgrade the software.

Internet Connection

Pre-configured DHCP option will work if:

ISP provides DHCP-based dynamic IP address delivery.

There is no requirement for teleworker-location support.

Use VPN server with static IP address for teleworker

7/28/2019 SMBEN20S07L02


PSTN Calls

Off-network or external PSTN calls:

Analog

FXO (pre-configured)

ISDN BRI (pre-configured)

T1/E1 PRI SIP trunk

7/28/2019 SMBEN20S07L02


IP Telephony Configuration

PBX mode

Incoming PSTN calls routed to anattendant console or an AA.

Phone users may be in separateoffices or geographically separated.

Phone users may use the telephoneto contact each other.

Keyswitch mode

All IP phones share lines.

Incoming PSTN calls can beanswered by any IP phone.

Phone users are generally closer inproximity.

Phone users have little need to usethe telephone to contact each other.

Changing the mode after installation requires reconfiguration of UC520.

SBCS Network Expansion

Expand wired LAN CE520 is used to expand a wired LAN

Initialized using Device Setup Wizard

Verify integrated autonomous WLAN

AP-521 is used to add an autonomousWLAN to add or to extend wireless coverage

Expand integrated WLAN Overage of UC520 with

autonomous AP can be expanded

One autonomous AP-521 cansupport 7 to12 wireless IP phones

Maximum of 3 APs supported

in autonomous WLANConfigure SmartPorts

Detects connected device

Applies template to optimizeswitch port performance for theattached device

7/28/2019 SMBEN20S07L02


Controller-Based Wireless Network

Initialize WLC526 controller

Add WLC526 to SBCS community

Create SSIDs for controller-based WLAN

Verify client association in controller-based WLAN

Additional Configurations for SBCS

Administrator username and password

Date and time

LAN and VLANs

IP routing

NAT Firewall

Security audit

7/28/2019 SMBEN20S07L02


VPN Service for Teleworkers

Configure VPN server

Configure software VPN clients

Initialize Cisco 871 router andconfigure a VPN client

Lesson Summary

The SBCS implementation of a secure voice and data networksupports up to 48 voice-users and up to 250 data-users withcentralized controller-based WLAN capability.

The SBCS implementation follows a logical sequence of stepsneeded to provision most common deployment scenarios.

The SBCS implementation requires that you ensure the completeinstallation of CCA and the availability of Internet connectivity andPSTN prior to installation or configuration of any of the networkingor VoIP components.

Module Summary

The process of designing an SBCS solution begins with a clearunderstanding of the SBCS solution, including the Cisco UnifiedCommunications for SMB and the SBCS management tools.

The process of implementing an SBCS network solution includesidentifying implementation components, describing the

provisioning sequence, and articulating the implementationprocess.
