Chapter 1 Solution Overview
Solution Features
Trunk Selection Policies in the TG
Trunk selection policies are applied to each TG, and allow the service provider to control the assignment
of trunks. The CA can be provisioned to select trunks in ascending order (default), select trunks in
descending order, select only even numbered trunks, select only odd numbered trunks or select the least
recently used trunk.
Glare Resolution Parameter in the TG
The glare parameter in the TG table is provisioned for bothway trunks. The glare parameter defines
whether a trunk group is master of odd numbered trunks, a trunk group is master of even numbered
trunks, a trunk group is master of all trunks or a trunk group yields any trunk in glare condition.
Subscriber Features
The Cisco BTS 10200 Softswitch supports subscriber features, including selected custom local area
signaling service (CLASS) features. Most of these features are defined in Bellcore LSSGR documents.
In general, Cisco BTS 10200 Softswitch features delivered via gateway clients behave identically to their
PSTN counterparts. Some features can be accessed and controlled by the subscriber using a handset and
vertical service codes (VSCs). VSCs are provisionable by the service provider.

Call Forwarding Features
Call forwarding is a group of features allowing incoming calls to a subscriber line to be forwarded to
another telephone number, including a cellular phone number, under various circumstances. Call
forwarding features allow a subscriber line to be forwarded to a number that itself can be forwarded. This
chaining of call forwards is allowed to a maximum of five different stations as long as none of the station
numbers appears twice in the forwarding list (in order to prevent loops). Before forwarding a call outside
of a zone or off net, the system must determine if the forwarding station already has an active call that
has been forwarded to the same destination. If so, forwarding is denied to the second call and a station
busy signal is returned to the caller.
Call Forwarding Unconditional (CFU)
CFU allows the user to forward all calls regardless of the status of the user’s line. A typical forwarding
address is voicemail, a remote telephone, or an attendant. A user whose station is idle, and that has CFU
activated, receives a reminder ring when incoming calls are forwarded, but is not able to answer the call.
A reminder ring is a half second burst of ringing. The reminder ring is not applied when the forwarding
station is off hook. CFU can be activated permanently at subscription time by the service provider or
activated and deactivated by the user using VSCs.
