Force10/Carrier Access/CAC Wide Bank 28 DS3 Mux fully redundant 930-0073, NEW!!!

Description

Wide Bank 28 Multiplexer
The Wide Bank 28 DS3 Access Multiplexer is available in quad Digital Signal Cross-Connect Level 1 (DSX-1) increments up to the maximum of seven quad cards supporting 28 DSX-1 connections.
Built-in options include 1:7 DSX-1 electronic redundancy, 1:1 controller electronics redundancy and
electronics redundancy with 1+1 network protection. The unit features solid-state fuse-less protection,
low power consumption, hot card swapping, DS3 and DSX-1 loopbacks for fault isolation,
built-in PRBS Bit Error Rate Testing (BERT), and integrated Network Interface Unit (NIU) functionality.
Configuration and maintenance testing is provided by a command-line interface or an SNMP
interface.
Features
• Single Standard Rack Unit (SRU) size (WxDxH: 17” x 10” x 1.75”).
• 75 ohm unbalanced BNC DS3 input standard.
• Dual independent –48 VDC power feeds with optional AC to DC power converter/battery
charger and eight-hour battery backup system.
• High-level integration reduces power consumption to less than 30W for a fully-redundant
configuration.
• Solid-state, fuse-less, overvoltage/overcurrent protection with automatic reset and
alarmed overcurrent protectors.
• Optional DS3 redundancy for either:
¨ Protected electronics (1:1), or
¨ Protected electronics and “hitless” network protection (1+1). Requires second independent
DS3 input.
• 1:7 by 4 DSX-1 electronic redundancy.
• Built-in automatic self test for all internal circuitry and transmission data paths to determine
network vs. electronic faults.
• Integrated Network Interface Unit (NIU) functionality provides DS3 loopbacks with AIS
toward the DSX-1 CPE.
• IP routing with Point-to-Point Protocol over a C-bit data link for management of remote
unit.
• DS3 C-bit path maintenance data link.
• DS3 C-bit far-end alarm, statistics, and control.
• The ability to use TFTP to upload and download a configuration file to a file system on
an IP host (This function provides the ability to easily load multiple Wide Bank 28 units
with the same configuration).
• Remote and local DSX-1 loopbacks with built-in PRBS for fault isolation on all 28 active
and 4 standby DSX-1 interfaces.
• Remote and local DS3 loopbacks with built-in PRBS test pattern generation for fault
isolation.
• Individual DSX-1 support for AMI or B8ZS line coding.
• Individual DSX-1 transmit Line Build Out (LBO) adjustments.
• DS3 Line Build Out (LBO) adjustments.
• DSX-1 transmit jitter attenuation and receive jitter tolerance.
• External critical and major/minor alarm relay contacts.
• DS3 clock source from DS3 network, internal Stratum 4E, or external coax input.
• Maintenance Service Option (MSO) that maintains T1 service on the spare DSX-1 quad
card while swapping failed electronics.
