1638- AND 1639-TYPE TELEPHONE SETS
1. GENERAL
1.01 This section contains connection informationfor 18- and 30-button telephone sets equipped
with 10-button TOUCH-TONEG dials, headset jacks
and used with station line concentrator. Connectioninformation for these sets was formerly containedin Section 502-636-413 which is hereby canceled.
1.02 Refer to the appropriate Reference sectionfor ordering and piece part information or
the section entitled 630-, 1630-, and 2630-SeriesTelephone Sets, Common Installation and MaintenanceInformation in Division 502.
1.o3 These sets are not intended for use with+type speakerphone systems.
2. CONNECTIONS
2.01 A 235A (MD) or B KTU is associated with
each 1638-type telephone set. A 236A (MD)or B KTU is associated with each 1639-type telephoneset. Because of the single common talking pair
and control lead patterns used in these sets, a lineconcentrator unit must be associated with eachtelephone set installed and cannot be shared, evenon a bridged stiation basis.
2.02 See SD-69499-01 (key telephone system, 6A,lA1 and 1A2 station line concentrators) and
ap]jropriate sections in Division 518 for connectionsto station line concentrators using 235- and 236-typekey telephone units.
2.03 When 400-type KTU’S are used as linecircuits, a 235B or 236B KTLT must be used
c)r ~ 2:j.; A or 236A KTU modified as shown in
I)ivision 518.
2.04 The P-90D033 Printed Wiring Board Assemblyused to provide a station busy lamp circuit
for 1638- and 1639-type telephone sets is intended
to mount in the 235- or 236-type line concentratorkey telephone unit associated with these sets.Connections to the telephone set are through theTA lead (Fig. 2 and 3). For connections to theprinted wiring board assembly, see section on stationline concentrators in Division 518 or refer to
SD-69580-01.
2.05 A 599B key may be used in the first keyposition to provide ringer or line cutoff
(Notes 5, 6, and 7, Fig. 2 or 3). When other usesare required they must be provided for by meansof an auxiliary relay separately mounted and
controlled by the turn key contacts since there areinsufficient mounting cord conductors to permitfull switching at the key.
K
~-R Some spade-tipped conductors org mounting cord leads are insulatedD with tubing which should be cut off
with electrician scissors or diagonalpliexs. Other conductors are insulatedwith stiffplastic pockets. Pinch openthe mouth to release the spade tips.
2.06 Because of insufficient leads from the firstmodule plug for use with a 599H key, the
supplemental hold feature cannot be used in thesesets.
2.07 To convert a key position from pickup(locking) to signal (nonlocking) remove the
screw detail P-1 OE837 entirely from the plungerat the key position to be converted. Make thenecessary wiring changes as shown in Table B.
Note: When converting keys in concentratortype telephone sets from locking to nonlocking,an insulating detail must be installed overthe key contacts associated with the operation
of the concentrator units. Refer to the sectionof modular keys in Division 512 for detailson installing the P-11E977 insulating detail.

v15uAL SIGNAL. cONNCcT lNDIc ATED LCAO TO AN AVAILABLE LAMP GROUND. WHCN 598A OR 656A KEY IS USED IN FIRST MODULE,INDICATED LEAD IS CONNECTED TO GROUND ON TERMINAL 5 OF TBI.
2. WHEN 598A OR 656A KEY IS U*O IN FIRST MOCAJLE, INDICATEO LEAO IS CCNNECTCD TO TERMINAL A OF TB6 ON 1638-TYPE SETS ANDTERMINAL 1A OF TB6 ON 1639-TYPE SETS.
3. WHEN 598A OR 656A KEy IS USED IN THIRD MOOULC OF 1638-TYPE TELEPHONE SET, (V-S) LEAD IS CONNECTED TO TERMINAL 5 OF TB3.4, TO CONVERT A KEY pOSi TION FR12M PICKUP (LOCK ING)TO SIGNALING (NONLOCKING) REMOVE THE SCREW DfTAIL P- IOE837 ENTIRELY FRW
THE PLUNGER AT THE KEY POSITION TO BE CONVERTED. MAKE THE NECESSARY CHANGES AS SHOWN IN CONVERSION TABLE A. TO CONVERT AKEY POSITION FROM NONLOCKING TO LOCKING, INSERT SCREW Of TAIL P- IOE837. WHEN CONVERTING A KEY rOR SIGNALING, PLACE AP- II E977 INSULATING OETAIL OVER THE 2 KEY CONTACTS ADJACENT TO KEY PLUNGER.
5. CUTOFF OF THE INTERNAL RINGER CAN BE PRWIOED USING THE 599B OR 657B KEY IN FIRST MODULE. TRANSFER BI LEAD FROM TERMINAL3 OF TERMINAL BOARD (FIG. 1) TO TERMINAL 6 oF TBI (F IG.2 oR 3) TRANSFER (R) LEAD FRoM TERMINAL 5 OF TBI (FIG. 2 oR 3) ToTERMINAL VACATED BY BI LEAO.
6. WHEN 599B OR 657B KEY IS USEO IN FIRST MODULE TO PROVIDE CUTOFF, SWITCHING, OR TRANSFER FEATURES, TRANSFER (Y-BR) LEADFROM TERMINAL 6 OF TBI TO TERMINAL SG OF TBVI. THESE SERVICE FEATURES ARE PROVIDEO BY AN AUXILIARY RELAY (229B KTU OREQUIVALENT) SEPARATELY MOUNTED AND CONTROLLED BY THE TURNKEY CONTACTS THROUGH THE LG5, C, S,SI LEAD.
7. CONTACTS OF TURNKEY CONNECTED TO TERMINALS 9 AND II kSJST Bf ISOLATED FROM EACH OTHER WITH INSULATING DETAIL P-13E443(FURNISHED wITH599B OR 657B KEY) TO PREVENT lNTERFCREtKE WITH WORKING CIRCUITS.
8. THE TURNKEY LAMP CAN BE ILLUMINATED IN ACCORDANCE WITH, OR INDEPENDENT OF TURt#(EY OPERATION.9. WHEN THE 617A KEY IS REQUIRED AS A DUAL-PURPOSE KEY, THE BRASS STRAP BETWEEN THE S1 AND SG TERMINALS OF THE KEY MAY BE
REMOVED. USE MIW CORO OR EQUIVALENT TO CONNECT SI TERMINAL OF 617A TO A DISSIMILAR GROUND OR A NONGROUNDED CIRCUIT.Io. CONNECT lONs FOR THE sTATt ON 13uSy LAMp FEATuRE ARE pROvt DED ON THE 235-AND 236-TYpE KTU. REFER TO THE sEcTION ON LINE
