(Release 6.1 or later systems, Hybrid/PBX mode only)
NOTE:
When Messaging-Waiting light updates are sent over PRI tandem
trunks, no TTRs are needed.

If more TTRs are needed to support the services listed above, 400 GS/LS
modules can be added. Each 400 GS/LS module provides four TTRs. Table 44
shows the estimated number of TTRs needed for the operation of the
communications system, depending on the system’s call volume and the use of
account codes. Additional TTRs may be required to support voice messaging
systems and delay announcement devices used by calling groups (see Tables 45
,
46
, and 47 below).
NOTE:
You must consider the call traffic across a private network when estimating
the number of required TTRs. This includes calls on analog tandem tie
trunks and T1-emulated tandem tie trunks. In addition, if your private
network includes Centralized Voice Messaging, you must consider the call
traffic coming across the private network for the voice messaging system
and the TTRs required for the updating of Message Waiting lights (Release
6.1 or later systems). For this updating, a TTR is required at the sending
end and the receiving end. If the systems in the private network are
connected by PRI trunks, no additional TTRs are needed.
