MPS 500 System Hardware Overview
Telephone Line Interfaces
The DTC can support up to eight digital T1 or E1 spans using a single digital communications
controller (DCC) plug-in module to connect to the public switched telephone network (PSTN). The
DCC supports either T1 (24 channels/span for a total of 192 lines) or E1 (30 channels/span for a
total of 240 phone line) interfaces.
Only one Digital Communications Controller (DCC/PLI) combination can be installed in the DTC.
Any line can be either incoming or outgoing, and all ports are non-blocking (that is, any port can be
bridged to any other port).
Digital Communications Controller (DCC)
The DCC provides the digital phone line interfaces for the system. It plugs into any of the two bottom
slots of the TMS. The DCC is dedicated for either a T1 or E1 system, and connects its phone line
interfaces to the PSTN (in the rear of the unit) with an RJ48M connector (up to eight spans) or eight
RJ48C connectors. A factory-ordered adapter is provided when RJ48C connectivity is required. See
Digital Interfaces
on page 195.
The DCC/CTPM/TPM card sets are also capable of interfacing with a telephony network using SIP/
RTP. A DCC/CTPM/TPM has no telephony connector on the front panel. Refer to
RTP
on page 29.
Qualified service personnel use the serial console connector for diagnostic purposes and for
verifying and configuring the boot ROM. See
connectors and indicators on the DCC front panel are reserved for future enhancement.
DCC-3000
The DCC-3000 is the newest version of the DCC family. The DCC-3000 adds two 10/100 Ethernet
ports and is available with or without full echo cancellation. The DCC-3000 can provide 256
channels of 64 millisecond (ms) echo cancellation. This feature is controllable by software on a per-
channel basis.
To determine if echo cancellation is installed on the DCC-3000 board, run the following command:
From the command line, run the command devlist.
If the command returns the following:
CARD_ID 503647401A_.5036436017, echo cancellation is installed.
If the command returns the following:
CARD_ID 503647402A_.5036436017, echo cancellation is not installed.
Note:
The card ID on your system may not match the card IDs in this example. However, the last digit
in the first series of numbers (1 in CARD_ID 503647401) is a 1 on boards with echo cancellation
and a 2 on boards without echo cancellation.
