Shared Diagnostic Control
Panel (SDCP) Installation

A single Shared Diagnostic Control Panel (SDCP) can

control up to eight carriers containing up to 128
compatible T1 CSUs, T1 DSU/CSUs, DSUs, or dial/lease
modems. The number of devices that can be installed in a
carrier or cabinet is reduced when Time Division
Multiplexer (TDM) or Multichannel Multipoint (MCMP)

circuit cards are also installed. A TDM or MCMP circuit
card (functioning as a multiplexer or digital bridge) is
physically attached to Models 3551, 3611, and 3616
DSUs and occupies a separate slot in the carrier. In a
single carrier without an NMS connection, an SDU is not
required to provide the SDCP interface. In a cabinet
configuration of two or more carriers, however, an SDU is
required in each carrier to connect the SDCP interface
from carrier to carrier. Figure 3-11 shows the SDCP and
Table 3-2 defines the SDCP status indicators.
