Networking Configuration Guide

• Reject it. If the user activates Do Not Disturb on Busy (DND) when the Call Offer request is

made, the request is removed from the telephone. The calling party is informed of the

rejection.

• Accept it. The Offer is accepted by releasing the active call.

Route Optimization

Route Optimization is a DPNSS 1 feature for BCM that allows calls to follow the optimum route

between two end PBXs. This allows efficient use of network resources.

Route Optimization is initiated by the system and is transparent to the user. However, the user may

see a call switch from an appearance on the telephone to another appearance key or from an

intercom button to the appearance key or vice versa. This occurs when BCM receives a Route

Optimization request and initiates a new call to follow the optimal route.

If a telephone is active on a private line call, the Route Optimization call being established may go

on a public line. This will cause a loss of privacy on that line.

Data calls are rejected by Route Optimization in order to ensure the data transmission is not

affected.

Certain situations result in Route Optimization not taking place. For example, calls that are using

Hold, Parking or Camp features do not undergo Route Optimization, and if a Route Optimization

call undergoes Diversion, the Route Optimization is dropped.

Setting Route Optimization

System programming is not required for the feature when BCM is working as a terminating PBX

system. However, BCM must have a private access code programmed that maps to a valid

destination code or line pool code on DPNSS lines. Further, Allow Redirect must be selected.

Loop avoidance

Errors in the configuration of a network may make it possible for a call to be misrouted, and arrive

at a PBX system through which it has already passed. This would continue, causing a loop which

would eventually use up all of the available channels. The Loop Avoidance service permits

counting of DPNSS 1 transit PBXs and rejecting a call when the count exceeds a predetermined

limit.

Note: A call cannot be offered to a telephone with DND active. The line

indicator for external incoming calls still flashes.

Note: Forward on Busy takes priority over DND on Busy. Call Offer cannot

be accepted by putting an active call on hold.
