H/S PERIPHERAL SHELF FRONT COVER The High Speed Peripheral Shelf front cover is an optional assembly for the High Speed Peripheral Shelf (90-2291-01). It is required for European Union EMC Class B compliance. (Note that Class B compliance is normally required for locations which are other than telecommunications centre ; if the location is a telecommunications centre, then the HSPS front cover may not be required.) The H/S Peripheral Shelf front cover is field installable, and the kit consists of mounting brackets, shelf cover and instructions for installation. The cover is perforated to allow all LEDs to be visible through the perforations. Locking clips at the top of the cover allow the cover to be removed to enable access to the OC12 line cards and FICs.

INTERNAL RING GENERATOR CBL KIT This cable kit is required when connecting 90-5946-01 (Ring Generator PSU) internally in a MainStreet Power Tray (90-3669-xx). This kit is intended for the following revisions of power tray; 90-3669-03/K, 90-3669-11/B and 90-3669-12/B. The MainStreet power tray has been updated to incorporate new functionality and the new cable kit is required.

ISDN CABLE This cable assembly is used to connect 90-9244-01 DUAL E1 CARD 3 (75 OHM), and 90-9244-02 DUAL E1 CARD 3 (120 OHM) with the distribution panel. The part number for the distribution panel is; 90-2635-02 DUAL E1 CARD 3 DISTRIBUTION PANEL. The cable and distribution panel together provide a means to connect the Dual E1 card circuits to external equipment.
