About this document
This document contains the installation procedures for attendant consoles,
telephones, and add-on modules. See Figure 1 for apparatus designations.
“Wiring installation” on page 3 includes information about the wiring for all
telephones and attendant consoles.
“Wiring installation” onpage 3describestheinstallationandremovalprocess
for QCW-type and M1250/M2250 attendant consoles.
“Telephones”on page 39provides procedures for installingand removing the
SL-1, M1109, M2000, M2006/M2008, M2016S, M2216, M2616, and
M3000 telephones.
“Add-onmodules” on page 81 includes installation and removal information
for all add-on modules and options for all telephones and attendant consoles.
Note: There are two distinct versions of Modular telephone sets—both
are supported. The versions can be clearly distinguished by the first four
letters in the model identification label on the bottom of the set. The two
types are the “NTZK” models and the “NT2K” models. When
appropriate, differences are noted in this document.

Wiring for telephones and attendant consoles
This chapter discusses the installation and removal procedures for wiring for
telephones and attendant consoles.
Each 500/2500-type telephone requires one pair of Z station wire or
equivalent. Each SL-1 telephone requires two pairs of Z station wire or
equivalent. You can use existing 16- or 25-pair connectorized cable. Each
attendant console requires a 16-pair cable terminated on an Amphenol
connector.
When zone cabling and conduit are used, assign a block of numbers or letters
to each zone (see Figure 2). Allow for growth when assigning blocks of
numbers.
Cable markers are normally an adhesive-backed cloth tape 1/2inches wide by
3-1/2 inches long (15 mm by 65 mm) with preprinted numbers.
For limits and cabling, refer to Figures 3 through 5.
For a list of terminal connections, see Table 1.

Telephone and attendant console installation
Procedure 1
Installing wiring
1Assign a number to the wire or cable used.
2Attach the assigned number to the wire or cable at the end nearest the
telephone, using a cable marker.
3Run the wire or cable between the telephone location and nearest
cross-connect point (if not previously run).
4Connect the cable or wire to the telephone connecting block.
5Designate the telephone connecting block.
6Cross-connect the pairs at intermediate cross-connect points (if
required) and terminate at the cross-connect terminal.
7Terminate leads at the cross-connect terminal and designate the
blocks according to the house cable plan.

Telephone and attendant console installation
Normal operating ranges
Telephones The normal operating range for SL-1 telephones, with and
without add-on modules, is 189 ¾ or 6000 cable feet (1830 m), whichever is
reached first. For example:
22 AWG wire range = 6000 feet (1830 m)
24 AWG wire range = 3700 feet (1125 m)
26 AWG wire range = 2300 feet (700 m)
The outside plant cable must not exceed 1 ¾ per mile, or 189 ¾ per
6000 kilometers.
SL-1 telephones equipped with a QKK1 extension kit have a maximum range
of 8000 feet (2440 m). For example:
22 AWG wire range = 8000 feet (2440 m)
24 AWG wire range = 5500 feet (1675 m)
26 AWG wire range = 3690 feet (1125 m)
The outside plant cable must not exceed 0.085 ¾ per mile, or 189 ¾ per
6000 kilometers.
Note: The 24 V and 15 V supplies can be obtained from the QUT1
centralized power supply located at the cross-connect terminal. A
separate fuse must be used for each set.
Meridian Modular Telephones have a maximum permissible loop length of
3500 ft (915 m), assuming 24 AWG (0.5 mm) wire with no bridge taps. A
15.5 dB loss at 256 kHz defines the loop length limit.

Attendant consoles The normal operating range for the QCW1C (or
earlier vintage) and QCW2A attendant consoles, with and without add-on
modules, is 189¾ or 6000 cable feet (1830 m), whichever is reached first. For
example:
22 AWG wire range = 6000 feet (1830 m)
24 AWG wire range = 3700 feet (1125 m)
26 AWG wire range = 2300 feet (700 m)
The normal operating range of the QCW1D and QCW2B (or later vintage)
attendant consoles is 8000 cable feet (2440 m) using cable rated at a
maximum of 0.085 ¾ per mile (1600 m). For example:
22 AWG wire range = 8000 feet (2440 m)
24 AWG wire range = 5500 feet (1675 m)
26 AWG wire range = 3690 feet (1125 m)
Thenormaloperating rangeof the M1250 attendant consoleis8000 cable feet
(2440 m) using cable rated at a maximum of 0.085 ¾ per mile (1600 m). For
example:
22 AWG wire range = 8000 feet (2440 m)
24 AWG wire range = 5500 feet (1675 m)
26 AWG wire range = 3690 feet (1125 m)
Note: The 24 V and 15 V supplies can be obtained from QUT1
centralized power supply located at the cross-connect terminal. A
separate fuse mustbe used foreach console. You can also obtain 24 V of
power from a QPC61 line card. The maximum resistance is 30 ¾.
The outside plant cable must exceed 1 ¾ per mile, or 189 ¾ per 6000
kilometers.
M2250 attendant consoles have a maximum permissible loop length of 3500
ft (915 m), assuming 24 AWG (0.5 mm) wire with no bridge taps. A 15.5 dB
loss at 256 kHz defines the loop length limit.
