Issue 7, September 1980
SERVICE
2630- AND 2631 -TYPE TELEPHONE SETS
CONNECTIONS AND MAINTENANCE
1. GENERAL
1.01 This section contains information for the
2630DA (MD), 26630DAM (MD), or 2630DAMSI
(18-button) and 2631DA (MD), 2631DAM (MD), or
2631DAMS1 (30-button) (Fig. 1, 2, and 3) telephone
sets. These sets may be equipped with different
modular key arrangements. The telephone sets
will accommodate 635-type or 658A keys, 76A
lamp sockets, and/or a679A (MD) internal
transmitter.
1.02 This section is reissued to
●Show the 2630DAM and 2631DAM telephone
sets MD
●Add the 2630DAMS1 and 2631DAMS1 telephone
sets
●Add new Fig. 1
●Revise Tables A, B, C, and E
●Add new 841364376 polarity guard.
1.03 $The new Scoded telephone sets are similar
to the previous type sets except they are
equipped with anew line switch which breaks both
the tip and ring side of the line. Previous t,ype
sets only broke the ring side of the line.q
2. CONNECTIONS
2.o1 The 2630- and 2631-type telephone sets were
equipped with a635A5C (5-line pickup and
hold) or a635AD5C (4-line pickup, cutoff, and hold)
key in the first module position. $Current 2630-
and 2631-type sets are only equipped with a635A5C
key in the first module position.t Contact strip
assemblies [required with sets equipped with a
D120K (MD) or D200S (MD) mounting cord] differ
between the two keys. If ordered for field
replacement, the 635AD5C is furnished with a
piggy-back adapter in the cut-off key position, for
storing the slate mounting cord plug associated with
the fifth line. The necessary contact strip assemblies
(840151039 and 840151047) will be shipped with
the 635AD5C and will replace the 840151120 and
840151138 assemblies supplied with the 635A5C
key.
Note: Contact strips are not required with
sets equipped with aD120M or D200AA
mounting cord or sets equipped with amodified
D120K or D200S mounting cord.
2.02 The 2630DAM (MD) and 2631DAM (MD)
modular telephone sets are similar to the
2630DA (MD) or 2631DA (MD), respectively, except
the modular G15A handset with its associated H4DU
cord and 616E jack assembly are used in place of
the hard wired G3A-type handset. OThe Scoded
sets also use the same modular handset, cord, and
jack.t
2.03 Because of the physical arrangement of the
635-type key, the contact strips do not extend
to the chaining switch. This requires asecond tip
and ring conductor to each module (except the
last). See Fig. 4, Sheets 1through 5.
2.04 The line conductors of the mounting cords
for these sets terminate in individual plugs
on aper line basis and are connected to the rear
of the keys. This permits rearrangement of line
appearances either in the set or at the key equipment
distribution point.
2.05 These sets can be used with 1A, lA1, 1A2,
6A, or 6B KTS. Refer to Table Aor B
for key modular arrangements.
NOTICE
Not for use or disclosure outside the
Bell System except under written agreement
Printed in U.S.A. Page 1

SECTION 502-612401
2.06 Refer to Table Cfor connections when
635AD5C cut off key is used in first module.
2.07 All line pickup key positions are convertible
to signaling or common signaling arrangements
by removing the 812857738 (P-28E773) screw from
key positions involved and making the necessary
wiring changes per Table D.
2.08 AKS-20419L1 (10 volt ac only) buzzer is
factory-installed for use as asecond audible
signal, when required. This arrangement uses (S-Y)
and (Y-S) mounting cord conductors from (0) binder
in the second module (Fig. 4).
2.09 These sets may be used with either the
3-type (MD) or 4A speakerphone systems.
2.10 Sets may be equipped for 3-type (MD)
speakerphone by the addition of a679A
(MD) transmitter in the 3rd (2630-type) or 5th
(2631-type) module (Fig. 5). Refer to Section
512-620-440 for necessary wiring changes and
connections.
2.11 When the 3-type (MD) speakerphone control
unit is located near the telephone set and
an internal transmitter (679A) is used, an A25B
connector cable should be plugged into the last
mounting cord plug and terminated on the 55-type
control unit terminal board.
2.12 To retain the maximum number of keys in
the CALL DIRECTOR telephone sets and
still have 3-type (MD) speakerphone feature, a666A
(MD) or 666B (MD) transmitter and 760A (MD)
loudspeaker may be installed as adjuncts to the
telephone set. Spare leads and hold key lamp
leads from the first module are used to supply
the external speakerphone function. When control
unit and telephone set are at same location, an
auxiliary mounting cord (D1OR) may be used.
Refer to Section 512-620-440 for complete connections
to 3-type (MD) speakerphone.
2.13 Refer to Section 512-730-400 for connections
to the current 4A speakerphone system.
2.14 The hold key in the first module is used
for normal hold functions or if required 1
Hold. An additional hold key can be installed in
the second key module location for Priority HoM.
The D-180411 Kit of Parts consisting of a635A5C
key, two contact strip assemblies, and apink plug
assembly must be ordered separately for Priority
Hold.
(a) Install as follows.
(1) Unplug and remove existing 635G5C key
from second module.
(2) Install contact strips and associated leads
if applicable (see note).
Note: Contact strips are not required with
sets equipped with aD120M or D200AA
mounting cord or sets equipped with amodified
D120K or D200S mounting cord.
(3) Place the pink plug assembly from the
kit of parts into the hold position on the
635A5C key. Insulate and store the white set
plug. Place the remaining set plugs into there
proper positions on the key.
(4) Make the necessary wiring connections
and modifications as shown in Fig. 6.
2.15 When required, these sets may be equipped
with apolarity guard. Polarity guards
should be installed only when specified by local
instructions for end-to-end signaling purposes when
battery and ground reversals are encountered.
An 840364376 guard assembly must be ordered
separately and connected as shown in Table E.
2.16 For station busy lamp feature with 3-type
(MD) or 4A speakerphone system, refer to
Fig. 7and 8, respectively.
3. MAINTENANCE
3.10 Maintenance of these sets should be limited
to replacement of items available through
regular supply channels. Refer to the reference
Section 502-603-100.
3.02 Maintenance of components of these sets
such as dials, ringers, etc. is covered in
sections pertaining to the particular component.
Maintenance information common to CALL DIRECTOR
sets can be found in Section 502-600-100.
3.03 Do not use sokents to clean plastic
parts of these sets. Use adamp cloth
only. If discolored, replace part.
