queue
Also, the slow dial tone may cause problems with transferring a call, joining
a call, and end-to-end signaling.
■ Additional touch-tone receiver (TTR) boards may be needed for the
system. The number of TTRs can be increased by adding 400 GS/LS or
016 modules, each of which provides four TTRs or by adding 008 OPT,
012, 800 GS/LS-ID, or 800 DID modules, each of which provides two
TTRs.
To determine the number of TTRs needed, perform a traffic study on the number
of outgoing single-line telephone calls/busy hour, and the number of incoming
calls/busy hour routed to applications such as MERLIN MAIL. Then use Table 3-5
to determine the number of TTRs required.
