Telephony Media Server (TMS)
The TMS is the core functional module of the Avaya Media Processing Server (MPS)
Series system. It provides a versatile platform architecture for a broad range of
telephony functions with potential for future enhancement. The basic TMS assembly
consists of a motherboard and mounting plate containing front panel connectors and
indicators.
The TMS motherboard provides most essential functions for telephony and telephony
media management, including network and backplane bus interfaces, local memory,
digital signal processors, tone generators, local oscillators, and Phase-Lock Loop
(PLL) for Computer Telephony (CT) bus synchronization with other TMS’ and the
chassis. The motherboard contains a riser board that allows up to four additional
modules to be plugged in. The TMS motherboard also contains six Digital Signal
Processors (DSPs) which can be configured for communications protocols and to
provide resources.
Phone Line Interface
A TMS contains at least one phone line interface card, which can be a single Digital
Communications Controller (DCC) (see page 29) or up to three Analog Line Interface
(ALI) (see page 30) (a second DCC will be present if Voice over Internet Protocol
[VoIP] is installed). Though digital and analog line interfaces cannot be combined in
the same TMS, multiple TMS systems can contain any combination of digital and
analog lines in the VRC. Any line can be either incoming or outgoing, and all ports are
nonblocking (i.e., any port can be bridged to any other port). The TMS can also be
populated with a Multiple DSP Module (MDM) (see page 31), in one or more of the
remaining open slots. Although the motherboard has local digital signal processors,
the MDM provides additional resources for systems that require them.
