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:

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.
