TEST CARD The Test Card provides metallic test access (Monitor <(>&<)> Split) to the customer loop on 3600 channel units. Test ac cess jacks are provided for the metallic test bus. Contains a DS0 interface for OCU-DP testing, with test access jacks and 5 pin connectors clock for Tx/Rx. Plugs into any UCS.

DEFLECTOR TRAY This assembly is used to deflect a hot air source away from an assembled 3600 or 3645 shelf (90-0010-05/10, 90-0662-03). The assembly requires 2 units ( 3 1/2 inches) of vertical space in a 19 inch rack. The 23 Adaptor (90-0571-03) is required for 23 inch rackmounting.

3600/45 KIT US-BASIC This installation kit contains cables/screws/antistatic strap/ground wire/spade lugs in order to install a 3600/45 single shelf into a rack or cabinet.

4WTO CHANNEL UNIT clei The 4WTO Channel Unit provides an interface of 600 ohms to the 3600 and 4-wire Transmission only (TO) circuits. Tx TLP levels +13 to -17dB and Rx TLP levels of +8 to -16dB. Attenuation range is 0.1dB steps. Requires 3600 equipped with Common Carrier card (90-1234-01). Sealing current 6mA min.

CHANNEL FILLER PLATES This package includes six channel unit filler plates. These are used to protect unused channel unit positions on a 3600 common carrier card (90-1234-01).

RS422 DCC (4 CCT) This assembly consists of four RS-422/CCITT V.11 interfaces, each independently programmable for V.35, X.21, V.36, RS-449 or RS-530. Individual circuit clocking for data rates of 1200 b/s to 1920 kb/s is provided by this assembly. This part is supported by Generic 1115 or greater.

SWITCH HSPS-2 CBL 25FT Identical to 90-1583-01 but 25ft in length. (Previously called DIN to DB37M 25FT).

UNIVERSAL DIST PANEL 19 inch rack mountable assembly which provides backplane access to four circuits from the RS-422 DCC (90-1549-01) via four adaptor modules (90-1642-01/02/03/04/05/06/07/08). Each module position can be independently provisioned with a different interface module to correspond to the type of interface each RS-422 DCC port has been configured as (ie. RS-530, RS-449/V.36, X.21 or V.35). Included are two 25 pair cables required to connect the distribution panel to the system.

UNIVERSAL DIST PNL EMC This assembly which is tailored for EMC Class B applications is a 19 inch rack mountable assembly which provides backplane access to four circuits from the RS-422 DCC (90-1549-01) via four adaptor modules (90-1642-01/02/03/05/06/07/08). Each module position can be independently provisioned with a different interface module to correspond to the type of interface each RS-422 DCC port has been c onfigured as (ie. RS-530, RS-449/V.36, X.21 or V.35). Included are two 25 pair cables required to connect the distribution panel to the system.

FASTBUS INTERCONN PANEL Panel that terminates up to 12 STP modules (90-1832-01) and optionally, 2 cascade modules; either STP (90-1651-01) or fibre (90-1653-01). Unused positions must be stuffed with bypass modules (90-1652-01). Includes backplane, card file, 2 STP modules (90-1832-01) and 13 bypass modules (90-1652-01)

FRE R4.3 clei FRE R4.3 FRE card with Release 4.3 frame relay software, which includes the DLCI multiplexing features. This card requires software generic P414-XX-XX. For software upgrades, order 90-7609-03 FRE S/W DNLOAD KEY P414-H3.
