E1-120 OHM LIM MODULE Variant of the E1 LIM (90-0568-01) which only supports 120 ohm interface. All other features of the E1 LIM are supported.

X.21 PRI-2 CARD This card presents a 30 channel, X.21/V.11 interface. Allows for faceplate (DB-15) or backplane (50 pin Champ) access. Configured as a Data Termination Unit (DTE). Supported bit rates are from 64 Kbps to 1920 Kbps. Also supported by this card in generic 1113 or greater is reduced framing overhead allowing for additional HCM data.

23IN DIST PANEL ADAPTOR Adaptor plate required to mount 90-0348-01, 90-0349-01, 90-1066-01 and 90-0350-01 distribution panels in 23 inch equipment racks. Only one required.

23IN CARD FILE ADAPTOR Adaptor plate required to mount 90-0010-02, 90-0010-04, and 90-0010-10 3600 shelves to 23 equipment racks. Only one required.

23IN ADAPTOR (2 UNIT) Adaptor plate required to mount the 90-0890-01, 90-0890-02, and 90-1236-01 assemblies or any other 19 inch rack mount assemblies of two vertical units, to a 23 inch rack.

DPM2 MODULE clei The Digital Processor Module-2 is a daughter card to the 27LC2 mother card (90-1184-05). Provides DDS or X.50 sub rate multiplexing functinality. One DPM2 module per 27LC2 card. This assembly contains a Telcordia CLEI (Common Language Equipment Identifier) label.

SWITCH I/F CARD PMX clei This card is required in each 3600 Peripheral Shelf pair (1 or 2 depending on Peripheral redundancy). For upgrade of a 3600 to a 3600 Peripheral Shelf, each 3600 Expander card is replaced by a Switching Interface Card. This assembly is similar to 90-0639-01 but allows for rear panel connectivity. This assembly contains a Telcordia CLEI (Common Language Equipment Identifier) label.

SWITCHING CARD (PMX) clei This card is a full replacement for the Switching Card (90-0640-01). It must be used with 3600 Switching Shelf Generic C111-07-00 or greater. This assembly contains a Telcordia CLEI (Common Language Equipment Identifier) label.

CLOCK CARD This card is used in the 3600 Switching Shelf to provide the system clocking (Stratum-3) for the 3600 Multi Shelf System. One Clock Card is required per 3600 Switching Shelf.

CLOCK CARD AM-2 clei Identical to 90-0641-01 but provides enhanced alarm I/O capabilities (AM-2). This assembly contains a Telcordia CLEI (Common Language Equipment Identifier) label.

HI SPEED PERIPH SHELF-2 This shelf consists of a card cage and backplane and accommodates up to eight E-3 Cards (90-1224-xx or 90-9751-xx). Uses up to two 90-0899-04 DC power supplies. Includes EMC front cover. Meets EMC class B requirements when EMC front cover is installed correctly.

SWITCHING I/F CBL 25FT Same as 90-0654-01 but with a total length of 25 feet.

SWITCH I/F CBL EMC 25FT Same as 90-0654-08 but with a total length of 25 feet.

SWITCHING I/F CBL 50FT This cable assembly is required to link the 3600 Switching Shelves (90-0662-01/03) using PMX Switching Card (90-0640-03) only to Peripheral Shelves (90-0010-05/09/10) equipped with PMX Switching Interface Card (90-0639-03), front panel connection.

DOUBLE BANDWIDTH MODULE clei This module is required on the Switching Card (PMX) (90-0640-03). It provides additional circuitry for 64MB/s throughput. This assembly contains a Telcordia CLEI (Common Language Equipment Identifier) label.

SWITCHING SHELF This is a 19 inch shelf assembly for use with either an AC or DC power shelf. This assembly allows for dual DC power input applications when used with the 90-0664-01/02 DC Power Shelves. This shelf is required for each 3600 Multi Shelf System and accomodates up to eight Switching Cards (90-0640-XX). Two shelves are required if the 3600 Multi Shelf System is configured for redundant switching operation. Consists of a cardfile and backplane. (Previously called Switching Shelf Dual DC I/P).
