40 Interworking requirements with CS 1000

For more information, see Nortel Mobile Communication 3100 and

Communication Server 1000 Solution Integration Guide (NN49000-315)

and Features and Services Fundamentals (NN43001-106).

CS 1000 feature interactions

The clients support a high availability configuration for improved

redundancy and failover. Configure the client with primary and secondary

proxy addresses that refer to different NRS-SPSs. The clients use an

options heartbeat to determine proxy availability. You can configure the

heartbeat time.

The clients also support existing SIP redundancy mechanisms in both

communication servers within a SIP deployment.

Call Forward No Answer feature interactions

It can be necessary to increase the Call Forward No Answer (CFNA)

timeout for mobile client users. The UEXT extends all calls to the MCG

3100. The MCG 3100 then presents the incoming call to the MCC

3100 client over the cellular data channel of the MCC 3100 (using

HTTP/HTTPS).

It can take a few seconds for the data transmission to reach the client,

depending on the current state of the mobile pone. If the CFNA timeout is

too short, users do not have reasonable time to (potentially) log on and

answer the call before the call server invokes CFNA and sends the call to

the CFNA destination.

To increase the CFNA timeout, configure the CS 1000 using LD 15 and

LD 11.

LD 15 configures the CFN0, CFN1, and CFN2 indexes:
