GENERAL This practice provides installation and operational procedures for the ADTRAN‚ Remote 1xN Pro-Cap protection switch multi-mount housing (P/N 1190860L1). See Figure 1. Pro-Cap initiates remote switching of a DS1 or HDSL circuit to a standby line following detection of a fault. This eliminates the immediate need for a vehicle dispatch to investigate trouble or provide standby service. The shelf also accommodates DDS and ISDN technologies but without protection. Section 61190860L1-5B Issue 2, January 2002 CLEI Code: NCM5NTDD_ _ Figure 1. 1xN Pro-Cap Pro-Cap can be used in conjunction with the ADTRAN Total Access® 3000 Carrier Class Broadband Multiservice Access Platform, or any standard Office Repeater Bay (ORB) with T1 or HDSL to provide a Protection Switching Network Interface (PSNI). The Pro-Cap housing accepts eight T200 type circuit cards or four dual slot T400 DS-1, HDSL, or HDSL2 circuit cards. The unit is a wall mounted assembly that provides convenient access to CPE connections. The assembly incorporates a circuit board backplane that provides a choice of amphenol connector or wire-wrap pins for facility wiring hook-up. The Pro-Cap accepts -48 VDC local power or a modular power supply that inserts into the POWER slot at the far right of the shelf. The power supply module includes an AC power cord that plugs into a standard 110 VAC grounded outlet. The Switch Customer Interface Module (SCIM) can mount to either the left or right side of the Pro-Cap housing to facilitate access to all CPE connections. 61190860L1-5B Trademarks: Any brand names and product names included in this document are trademarks, registered trademarks, or trade names of their respective holders. The SCIM can be locally powered by -48 VDC, or span powered from the standby unit in slot 8 if equipped for span power. Slide switch S1 selects between local or span power. CPE receive and transmit connections are either amphenol or RJ-48C jacks. Revision History Issue 2 adds Auto-Protect information when the Pro-Cap is configured in a Total Access 3000 network. Features The 1xN Pro-Cap includes these features: • Protection module. • Compact and lightweight assembly that accommodates eight T200 mechanics or four T400 mechanics modules. • Reversible SCIM for right side or left side assembly. • Prewired backplane to minimize wiring errors and installation time. • Protect module can function as standard channel module. • Dedicated slot for modular power supply. • LEC facility connections are made by 25-pair Amphenol XMT/RCV connectors or wire-wrap pins. • CPE connections are made to RJ-48C modular jacks or 25-pair Amphenol XMT/RCV connectors. • Auto-Protect Switching with Total Access 3000 applications. • Swing open tinted Plexiglas front cover. • Available with key-locking metal cover (List 4 Option). • Includes standard 10-year warranty. Physical Description The 1xN Pro-Cap consists of four elements: 1. Mounting-Plate The mounting-plate attaches to a customer premises backboard. 2. Shelf The shelf has slots for seven channel modules, one standby (protect) module, and one power module, plus two external edge connector...
