A single TMS can support up to eight digital T1 (24 channels/span for a total of 192

lines) or E1 (30 channels/span for a total of 240 lines) spans by using an individual

DCC to connect to the Public Switched Telephone Network (PSTN). If some of the

lines are used exclusively for IVR resources, one or more spans may be dedicated.

Spans dedicated as such are connected directly in clear channel protocol. Supported

digital protocols include in-band T1/E1 and out-of-band SS7 and ISDN.

In addition a TMS can support up to 72 analog lines by using three ALI boards (24

lines per ALI). The standard analog interface supports common two-wire loop-start

circuits.

Information on configuration and application of phone line protocols and interfaces

can be found in the Avaya Media Processing Server Series Telephony Reference

Manual.

Digital Communications Controller (DCC)

The DCC provides the digital phone line interfaces for the system. It can be plugged

into any of the four slots of the TMS. The DCC is dedicated for either a T1 or E1

system, and connects to the PSTN via an RJ48M connector (up to eight spans).

The DCC is also capable of interfacing with a telephony network using VoIP. A

DCC-VoIP has no telephony connector on the front panel. Only one DCC is typically

installed in the TMS, unless the system is also using VoIP, in which case the

DCC-VoIP will also be installed. The DCC cannot be combined with an ALI in the

same TMS.

A serial console connector is provided for diagnostic purposes and for verifying and

configuring the boot ROM (see Verifying/Modifying Boot ROM Settings on page 252

for details). Other connectors and indicators are provided on the DCC front panel but

are reserved for future enhancement.
