Digital Trunk Controller

The digital trunk controller (DTC) assembly is comprised of the telephony media server (TMS)
motherboard, the PLI, and the optional DCC/TPM/MDM cards. The DTC is responsible for lower-
level functions, such as telephone line signalling, host communications, use of shared resources,
and message recording/playback.
The following diagram is a schematic of the DTC.

Telephony Media Server

The telephony media server (TMS) is a subcomponent of the DTC and refers to the TMS-2500
motherboard. The TMS motherboard supports optional daughterboards (TRR, PLI, DCC, MDM, and
so on), which are mounted to provide expanded resources and functionality, such as a PCM
interface, a SIP/RTP interface, and an SS7 interface.
