Table 2–2 lists the modules that supply TTRs to the MERLIN LEGEND
Communications System.
Table 2–2. Modules with Touch-Tone Receivers
A voice messaging system (VMS) requires a certain number of TTRs in addition
to any system requirements for TTRs. The number of TTRs depends on the
number of ports used by the voice messaging system (see Table 2–3
). TTRs are
also required in private networks using E&M, T1 tie, and tandem tie trunks.
NOTE:NOTE:NOTE:
A VMS
cannot
be directly connected to the 008 OPT module. However, the
TTRs supplied by the 008 OPT module can be used by the VMS.
Table 2–3. Touch-Tone Receivers Required by Voice Messaging Systems
1. If a 12 port MERLIN LEGEND Enhanced Service Center is used, 8 TTRs are required.
