System migration
When particular Meridian 1 systems are upgraded to run CS 1000 software
and configured to include a Signaling Server, they become CS 1000
systems. Table 1 "Meridian 1 systems to CS 1000 systems" (page 14) lists
each Meridian 1 system that supports an upgrade path to a CS 1000 system.

•modem with autodial capability
Note: This configuration is the least reliable due to lockup problems
inherent in Smart Modems from power spikes and noisy lines. To
increase the reliability on this configuration, use a constant power
source when powering the modems. Also, verify that TIE lines meet data
grade specifications. Nortel takes no responsibility for ISL D-Channel
outages due to modem lockup.

20 ISDN Primary Rate Interface equipment overview
•QMT8 Asynchronous Data Module (ADM), QMT11 Asynchronous/Syn-
chronous Interface Module (ASIM) or QMT21 High Speed Data Module
(HSDM)
•Data line card
64 Kbit/s Clear Data Hardware
The QMT21 High Speed Data Module (HSDM) is required in the clear-data
pathway to support the 64Kbit/s clear-data function. One module is required
at each system end of any connection.
D-Channel Handler description
This section provides descriptions of the D-Channel (DCH) cards, the MSDL
card, and the Downloadable D-Channel Daughterboard.
NT6D11 DCH
Power requirements
The power requirements for the NT6D11AB/11AE/AF DCH are:
•+5 volts at 3 amperes
•+12 volts at 75 milliamperes
•-12 volts at 75 milliamperes
DCH/PRI interface
The NT6D11AB/AE/AF DCHs connect to the PRI2 cards by means of a
special RS422 cable, the QCAD328A, which is a special RS422 cable; refer
to "QCAD328" (page 300) of the Cabling chapter for more details.
DCH faceplate
NT6D11AB/AE/AF DCHs have one Light Emitting Diode (LED), to indicate
an active or inactive state, and two external connectors:
•Port J1 is a standard asynchronous port providing an interface for
non-PRI applications.
Note: This connection will not support an Add-on Data Module (ADM)
terminal.
•Port J2 is the D-Channel Interface port.
Figure 2 "NT6D11 DCH faceplate layout" (page 21) shows the faceplate
layout.
