1. 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.
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.
