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. **********5 YEAR WARRANTY**********
