Installing a Modular TDM or MCMP
This section describes the procedure for adding a
modular TDM or MCMP circuit card onto a Modular
3611 DSU and then into a COMSPHERE 3000 Series
Carrier.
A connector module, which is supplied with each
modular TDM or MCMP card, has six ports (labeled
Port 1 through Port 6). The connector module is shown on
the right in Figure 3-4. When the connector module is
installed in a COMSPHERE 3000 Series Carrier, you can
remove the modular DSU with a TDM or MCMP without
disconnecting the DTE cables at the rear of the carrier.
Each port on the connector module is a DB25
connector which provides the EIA-232 DTE interface. In
addition, a 26-pin high-density D-type connector is
located at the top of the connector module which provides
the V.35 interface for either Port 1 or an aggregate data
path. This connector requires a 6-port V.35 Interconnect
Cable which converts the 26-pin high-density D-type
interface to the standard V.35 34-pin interface. The 6-port
V.35 Interconnect Cable (part number 035-0174-0031)
must be ordered separately.
