System Requirements for Touch-Tone Receivers
Table 3–4 estimates the total number of TTRs required in the system, based on
call volume and whether the system uses account codes. The call volume per
hour in this table includes all calls originating from single-line telephones, calls
on tie lines, incoming remote access and DID calls.
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.
