Branch Office configuration

Configuring the trunks and lines

To install the line and trunk cards, if the Branch Office is a converted Small System, refer to Avaya
Communication Server 1000E Installation and Commissioning, NN43041-310.
To configure lines, refer to Avaya Communication Server 1000E Installation and Commissioning,
NN43041-310.
If the Branch Office is a converted Small System, refer to Avaya Communication Server 1000E
Installation and Commissioning , NN43041-310.
To install and configure Virtual Trunks on the Branch Office, refer to Avaya IP Peer Networking
Installation and Commissioning , NN43001-313.

Adding the Branch Office endpoints to the NRS database

The Branch Office feature requires the Network Connection Service (NCS) to redirect a Branch User
to the main office. The NCS allows the TPS to query the NRS using the UNIStim protocol, and the
TPS then redirects the Branch User accordingly. The NCS is a component of NRS, and is enabled
using the NRS Manager.
Each Branch User ID (BUID) must be entered in the Branch Office numbering plan to point to the
main office. Avaya recommends that each BUID be a public DN (that is, a number in the public
directory). Therefore, the BUID points to both the Branch Office and the main office. However, there
may be situations where a separate BUID may be required, such as in a Multiple Appearance DN
(MADN) configuration. In this case, the separate BUID may not be a public DN and explicit
configuration is required. The BUID must be added to the numbering plan to point to the main office.
If VO User ID or BUID is configured for Coordinated Dialing Plan DN (CPD_DN) then it should be in
one of the following formats:
• CDP_DN without Local Steering Code/Distant Steering Code
• Access Code + HLOC (Home Location Code) + CDP_DN
Avaya recommends that routing entries should be set up to consider the cost of redirection. In
Normal Mode, the least cost route should be used to redirect the Branch User to the main office. For
survivability, an alternate route should be used, such as that route with a second-least cost.
Refer to Avaya IP Peer Networking Installation and Commissioning, NN43001-313 for the
appropriate procedures.
