BCM INTEROPERABILITY WITH COMMUNICATION SERVER 1000 AND MERIDIAN 1 WITH IP TRUNK

ERSION 5.2 JUNE 2007 PAGE 13 OF 20

Known Issues with

CS1000 4.5 and 4.0

Description BCM 3.7 and BCM 4.0 and

BCM50R1 BCM50R2

Notes:

• Communication Server 4.5/4.0 provides an optional MCDN Information Element that

signals the Virtual Private Network Identifier and the Bandwidth Management Zone

over IP Peer Virtual Trunk routes to allow Call Servers to coordinate codec selection

appropriately for different Internet Telephones depending on network location. This

VPNI IE is not generated or used on BCM systems. In SRG mode, this VPNI IE is

generated so that the Communication Server 4.5/4.0 can determine which zone calls

are originated or destined for bandwidth management. However, SRG does not

process any incoming VPNI IE and does not provide bandwidth management

capabilities.

Server Functionality

(NRS)

Notes:

• BCM uses the Registration Time-To-Live (TTL) value in the BCM Gatekeeper

settings to establish the point at which re-registration is attempted. If no response is

received from the primary NRS, the BCM will send up to two additional registration

requests, each 12 seconds apart, at which point the alternate NRS registration process

is initiated, with a total elapsed time 24 seconds longer than the TTL setting.

• The Communication Server NRS also supports a mechanism to instruct gateways to

switch to the Alternate NRS for maintenance purposes. Communication Server

4.5/4.0 gateways and IP Trunk 3.01 nodes will re-register to the Alternate GK almost

immediately, while the BCM will treat the condition as a failure, and use the

Alternate NRS failover procedures identified above.
