! CAUTION:
Do not plug the A/C adapters into a 240-vac outlet because
you will damage the adapter and the module. You must first
obtain an adapter to convert 240 vac to 120 vac.
5. Administer the line (if applicable) and station ports by using the
procedures in the 
DEFINITY® Communications System
Generic 3 Implementation Guide, Issue 1,
 document #555-230-
655.
nIf the Standalone Switch Module is connected to an analog
circuit pack, you should administer the line port for Direct
Inward Dialing (DID) operation.
nAdminister the station port as you would any other on-
premise station.

Connecting the Multi-Mount
Rack and Rack-Mount Modules
Connections to the Multi-Mount Rack are done via the back panel
(see Figure 3-2). The back panel elements are:
n50-pin Amphenol port connects the Multi-Mount Rack to the
DEFINITY ECS analog circuit pack and the central office lines
for transmission of the signaling information. The circuit packs
to which the Rack-Mount Switch Modules can be connected are
the 8-port TN742 and the 16-port TN746.
nAdministration Port connects the Multi-Mount Rack and Rack-
Mount Modules to the administering computer or terminal.
nDB9 ports for each Rack-Mount Module (A–L) provide for
simultaneous RS-232 communication between equipment at
the off-premise site and the on-premise site.
nFour-position connector for the power supply that has  a
matching plug on the power supply. The connector is polarized
and can be connected only in one way.

Installing the Multi-Mount Rack
Connections to the port on the DEFINITY ECS and to the analog
line are made through a 50-pin Amphenol connector, which the
customer must supply. This connector provides the connections for
all 12 Rack-Mount Modules (listed as Cards A–L). See the
DEFINITY® Communications System Generic 3, Installation for
Single-Carrier Cabinets 
manual, document #555-230-894,
comcode #107595423, for complete installation requirements.
Table 3-2 shows the 50-pin connector pinout.
NOTE:
The pin connections for the 50-pin connector are not polarity-
sensitive. Therefore, if you reverse the tip and ring pair, service is
not affected.

Follow these steps to install the Multi-Mount Rack:
! CAUTION:
Do not plug the A/C adapters into the electrical outlets until
instructed to do so in the following procedure.
1. Create a cross-connect or wall field so that the 50-pin
Amphenol cable can be used to connect the DEFINITY analog
circuit pack (the 8-port TN742 or the 16-port TN746) and
dedicated central office lines to the 50-pin Amphenol port on the
Multi-Mount Rack (see Figure 3-3). See the 
DEFINITY®
Communications System Generic 3, Installation for Single-
Carrier Cabinets 
manual for complete instructions.
Figure 3-3. Cross-Connect or Wall Field
2. Connect the Administration Port to the system administrator’s
computer or terminal by using an RS-232 DB9 cable. 
						

							Installation
3-14   Issue 3   July 1997 3. Connect the AC adapter provided with your system to the Multi-
Mount Rack. Plug the adapter into a standard 120-vac electrical
outlet.
! CAUTION:
Do not plug the A/C adapters into a 240-vac outlet because
you will damage the adapter and the module. You must first
obtain an adapter to convert 240 vac to 120 vac.
Installing the Rack-Mount Modules
The Rack-Mount Modules slide into the Multi-Mount Rack. The
Multi-Mount Rack holds up to 12 Rack-Mount Modules. Follow
these steps to insert the Rack-Mount Modules:
1. Line up the top and bottom edges of the Rack-Mount Module
circuit board with the top and bottom grooves on the Multi-
Mount Rack. The top edge is the one with the ejector button,
and the bottom edge is the one with the light-emitting diode
(LED).
2. Gently push the Rack-Mount Module into the Multi-Mount Rack
until the connector on the back of the Rack-Mount Module
seats itself into the connector on the Multi-Mount Rack.

Issue 3   July 1997   3-15 Administering the Line and Station Ports
Administer the line (if applicable) and station ports by using the
procedures in the 
DEFINITY® Communications System Generic 3
Implementation Guide, Issue 1,
 document #555-230-655.
nIf the Multi-Mount Rack is connected to an analog circuit
pack, you should administer the line ports for Direct Inward
Dialing (DID) operation.
nAdminister the station ports as you would any other on-
premise stations.

Connections for Data
Transmission
By using the COM 1 port on the Switch Module, you can establish
simultaneous data transmission between the off-premise location
and the on-premise location. Typically this involves a personal
computer (a “remote data terminal”) at the off-premise location
communicating with an RS-232 server link on-premise (at the
DEFINITY ECS location).
NOTE:
The factory setting for the data transmission rate is 9.6 kbps. If the
user at the Remote Module changes the rate to 19.2 kbps, the
Switch Module rate will also change to 19.2 kbps. Any change must
be done from the Remote Module.
To connect the server at the on-premise location to the COM 1 port
of the Standalone Switch Module, use a straight-through, 9-pin RS-
232 cable (see Figure 3-4).
To connect the on-premise server to the Multi-Mount Rack, again
use a straight-through, 9-pin RS-232 cable. However, in this case
the cable connects to the DB9 connector on the back of the desired
Rack-Mount Module.
