INSTALL TERMINALS
When installing terminals at workstations, consult the Voice and Data Station
Records Form to make sure that you are connecting the right terminal type at
each workstation.
In a replacement installation, single-line and MET voice terminals already in
place may not need to be replaced, although the MET labels change.
Installation is required only for new terminals ordered. Standard MET sets
(2990 Series) require a ZD8AJ-87 (grey) or ZD8AJ-50 (beige) adapter cord 
between the modular cord and the wall jack. The 12-button MET set does
not need the ZD8AJ-87 adapter cord. (Only 10-button and 12-button MET
sets may be used with System 25. Also, the set with busy lamp field will not
work unless modified.)
Terminals located in the same building can be connected to the system as

terminal/adjunct combinations do not.
For MET sets, use a 400B2 Adapter and a 2012D Power

The ATL Cordless Telephone is powered by 110 V ac
receptacle that is not under control of a wall switch.

Unpack each voice terminal and ADU and examine them for damage.
Arrange 7300H Series terminals and single-line terminals with
appropriate ADUs (see Note).
Note:The Z3A1 ADU is equipped with a male RS-232C
connector, and the Z3A4 ADU is equipped with a
female RS-232C connector. The choice depends on
the data terminal since both ADUs are used with
single-line voice terminals.
At the workstation, connect the ADU’S cable to the RS-232C
receptacle on the data terminal.Always tighten the screws or other
fasteners on this connection. If these connections are not properly
fastened, the Data Line CP port may be falsely busied out.
Connect the voice terminal to the modular jack labeled Telephone on
the ADU.
Connect a D8W-87 modular cord between the jack labeled Wall Jack
on the ADU and the wall jack.
For 7300H Series terminals, use a D6AP Cord to connect a KS-
22911 Power Unit to the power jack on the Z3A5 ADU.

Before placing the base at the designated location, the following things must
reconsidered.
— The base unit should be located at least three feet from any metal
source.
— The base should be located so that no metal objects are in the line
of sight to the operating area of the handset.
— The base should be located at least six feet from computing
equipment and electromagnetic sources.
Install the ATL Cordless Telephone using the documentation provided with
the telephone.

Out-of-Building Voice Terminals (TN742, TN746B in R3V2)
A single-line voice terminal may be located in another building in a campus
environment within a loop resistance of less than 1300 ohms (including the voice
terminal). These terminals require primary and secondary protection devices.
Only a TN742 CP can be used.
1.At the remote location, connect the single-line terminal to a 103A
connecting block, using a modular telephone cord.
2. Using 4-pair inside wiring cable, connect the 103A connecting block to
primary and secondary protection devices. (See Table 2-B.)
3. Run the cable from the remote protection device to the System 25
equipment location.
