Genuine Original Westell Real Time Performance T1 Network Interface Card B90-311580. The Westell 3115-80 Issue B T1 Network Interface Unit with real-time Performance Monitoring serves as an interface between a T1 metallic span, or a customer premises-based fiber multiplexer, and the intra-building Customer Premises Equipment (CPE). The 3115-80 Issue B is a member of the Westell PROACT family of T1 NIUs that provide standard maintenance loopback plus collection and reporting of DS1 performance statistics.

Part Number: B90-311580
 

Features:

• Full-featured T1 NIU loopback device plus detailed T1 performance monitoring and reporting at the customer facility interface;
• Loopback activation and deactivation using inband (unframed or SF/ESF framed) or ESF Data Link codes;
• Addressed loopback control with 16-bit pattern for TER (T1 Extension Repeater) applications;
• CPE-to-Facility LBO provisionable from 0 to 22.5dB in 7.5 dB increments;
• Alternate self-aligning CPE-to-Facility LBO that automatically protects the network from a mis-optioned customer LBO;
• Enhanced sectionalization capabilities via AIS-CI and RAI-CI alarm signals as defined by T1.403-1998;
• Derives and maintains DS1 performance statistics independently for each direction of transmission;
• Supports both 30-day stored as well as real-time performance reporting modes;
• Flexible DS1 performance reporting options:
  Local, non-intrusive access to PM parameters via a front-panel local craft interface port;
  Remote, intrusive access during loopback to PM parameters via TL1 commands and responses in the ESF Data Link;
  Remote, non-intrusive access to PM parameters via TL1 commands and responses in the Data Link, by use of a Test Head, without affecting customer payload;
  Remote, non-intrusive real-time reporting of PM parameters via 1-second NPRM or SPRM reports in the Data Link per ANSI T1.403-1998;
• On board test pattern generator;
• Notepad craft screen for documenting information about the circuit;
• User-configurable alarm threshold craft screen;
• Integral real-time clock provides time stamping of all performance information;
• Selectable powering option (via jumper option) for span or local power;
• Front-panel test points for measuring span current;
• Monitor-type bantam jacks on FAC IN and FAC OUT ports for transmission path monitoring;
• Front-panel craft interface port (serial RS-232, VT-100) for local, non-intrusive PM extraction, unit set up, test code generation and circuit maintenance.
