Processor Data Mo dules (PDMs) are connected to TN754B d i gital line circuit 
packs and are mounted individually or in a 71A data mounting. Other digital-line 
circuit packs may be required in some countries. Each 71A d ata mounting can 
contain up to eight modules. This document contains only the information 
required to connect the modules to the switch. Module installation and testing 
information is contained in 
AT&T System  75  User’s  Guid e—Processor Data 
Module
, 999-700-028.
The data mounting is connected by an A25D/B25A c a ble through the cross-
connect field to a TN754B digital line circuit pack. The modules can also be 
mounted and connected individually through the cross-connect field.

Refer to the vendor’s documentation for connecting to the Property Management 
System (PMS). The option switches on the Processor Data Module (PDM) must 
be set in accordance with the requirements for the customers Property 
Management System (PMS).
A journal p rinter can b e used. The connections for the printer are the same as for 
the Property Management System (PMS). Refer to the vendor’s documentation 
for connecting the Processor Data Modules (PDMs) to the printer and for setting 
the o ption switches. The switches must b e set according to the requirements for 
the printer.
The Property Management System (PMS) interface and the journal printers can 
be installed using Asyn chronous Data Unit (ADUs). The connections are the 
same as for a customer-provided data terminal (Figure 9-32 on p a ge 9-61).
Connections to a G3i switch can be switched connections through an 
Asynchronous Data Unit (ADU), through a modem or through the 7400A/B or 
7500 d ata modules.+

Using Asynchronous Data Unit (ADU)
Requirements
The interface between the switch and the customer’s data terminals and host 
computer can be through Processor Data Mo dules (PDMs). Refer to section on 
installing Processor Data Modules (PDMs) for d etails.
Asynchronous data terminals, however, can b e connected through a Z3A 
Asynchronous Data Unit (ADU) to a TN726B data line circuit pack (Figure 9-32). 
Normally, the data unit is powered from the connected data terminal. The d ata 
unit can also be remotely or locally p owered using a 2012D transformer 
equip ped with a 248B adapter. Data units connected to receive-only printers 
always require external p ower. The need for external p ower must b e d etermined 
experimentally for d ata units connected to other devices. For more information 
on d ata unit installation, refer to the 
Z3A Asynchronous Data Unit User’s Manual, 
555-401-701.
Installation
1. Determine data unit port assignment from Data Module Form:
2. Connect the RS-232 plug on the data unit to the data terminal. EXAMPLE:   Port Numb er 2 B 02 01

Install Station Message Detail 
Recording (SMDR)/Call Detail 
Recording Unit (CDRU) Interface
The interface between the switch and Station Message Detail Recording 
(SMDR) can b e through a Processor Data Module (PDM), Trunk Data Mo dule 
(TDM), or 212-type modem. 
For connections b etween the switch and the Processor Data Module (PDM) or 
Trunk Data Module (TDM), refer to the section on installing Processor Data 
Modules (PDMs).
The connection between the switch and the 212-type modem is the same as for 
external ringing (Figure 9-11). When  a  212-type modem is used, an external 
pooled modem circuit pack must be provided. One of the pooled modem’s 
conversion resources is dedicated to the Station Message Detail Recording 
(SMDR) output device.
Connections between the G3i switch and an Asynchronous Data Unit (ADU) or 
data module are the same as for remote administration devices such as the 
Generic 3 Management Terminal (G3MT). These connections are shown in 
Figure 9-32 and Figure 9-33. All such connections require the mo de 2 to mo de 3 
conversion resource shown in these figures.
Administer your connections as d escribed in 
DEFINITY Communications System 
Generic 3 V2 Implementation
, 555-230-655.
A TN726B data line circuit pack may also be used. If so, Processor Data 
Modules (PDMs), Trunk Data Modules (TDMs), or 212-type modems are not 
required for the d ata terminal e quipment (DTE). Connections between the switch 
and the Station Message Detail Recording (SMDR) output receiving device is 
the same as a customer-provided data terminal (Figure 9-33).
The Station Message Detail Recording (SMDR) output device c an b e connected 
directly to the data communications equipment (DCE) connector on the rear of 
the control carrier. This connection is made using a RS-232 c a ble. A Processor 
Data Mo dule (PDM) or Trunk Data Module (TDM), modem, or Asynchronous 
Data Unit (ADU) is required.

Figure 9-33 shows the c a bling required to connect the TELESEER unit, printer, 
or customer-provided data terminal equipment (DTE) for an AC-powered single-
carrier cabinet. The M25B/RS-232 cable connects to the PI connector on the 
TELE SE ER  unit. 
!CAUTION:
All peripherals connected to a DC-powered switch through the 
asynchronous Electronic Industries Association (EIA) RS-232 d ata terminal 
equipment interface on the Processor Port Network (PPN) A or B carrier or 
the Exp ansion Port Network (EPN) maintenance circuit pack require an 
Electronic In dustries Association (EIA) 116A ground isolator. Plug the 116A 
ground isolator into the RS-232 interface connector (labelled DTE on the 
back of cabinet). The cable from the peripheral equipment is then plugged 
into the o pto-isolator. Figure 9-33 shows the c onnections for a DC-powered 
single-carrier cabinet.
The a p paratus code for the isolator is 116A ground isolator and the AT&T 
Comcode is 106005242.
