66-TYPE HARDWARE
Installing Dial Dictation Equipment
The procedures and requirements for installing the Recorded Telephone Dictation feature is
the same as for the Recorded Announcement feature for analog access (see Figures 4-88 and
4-89) and the same as Music-on-Hold for auxiliary trunk access (see Figures 4-84 and 4-85).
The port assignment for the feature is on the Station Record Form when a TN742 or TN769
circuit pack is used. The port assignment for the feature is on the Trunk Group Form For
Customer Provided Equipment when a TN763 circuit pack is used.
Installing 3270 Data Modules
Requirements
The 3270 data module consists of a family of protocol converters that allow 3270-type
terminals to communicate with a host computer through the system. The three types of 3270
data modules are the following:
3270A (Asynchronous)
3270C (Controller)
3270T (Terminal)
3270 data modules are connected directly to TN754 Digital Line circuit packs. This manual
contains only information for connection to the data modules from the system switch.
Installation and testing information for the 3270 data modules is contained in the 3270
DATA MODULE—Coaxial-to-DCP Protocol Converter—Product Guide, 999-700-520.

Carrier Slot Circuit
Install jumper wires at cross-connect field.
Run and connect 4-pair line cord (modular plug on both ends) from information
outlet to data module (see Figure 4-94).
Administer per AT&T System 75 and System 75 XE Implementation and AT&T
System 75 and System 75 XE Administration.
Connection to 3270C Data Module (Figure 4-95)
1.
Identify carrier slot and label both ends of switch cable.
2.
Connect cable to appropriate port carrier slot and dress cable down sides of
cabinet.
3.
Run and connect B25A cable from bottom of the switch cabinet through cable slack
manager, if provided, to a connecting block in the purple trunk/auxiliary field.
4.
Run and connect B25A cable from connecting block in the yellow Trunk/Auxiliary
Field to location of 3270C data module (see Note).
