VCL-SafeCommTM, 16 E1 Links (48 E1 Ports)
(1+1 Automatic Protection Switch)

Product Overview

The VCL-SafeComm, 16 E1 Links (48 E1 Ports), 1+1 Automatic Protection Switching Equipment may be used to protect upto 16 E1 Links (48 E1 Ports), point-to-point links and provide an alternate communication route to each E1 Link between any two E1 points. In the event of the failure of the primary (Main) E1 communication route, the VCL-SafeComm 16 E1 Links (1+1 Automatic Protection Switching Equipment) automatically switches the E1 traffic to a secondary (standby) E1 route. The VCL-SafeComm, 16 E1, 1+1 Automatic Protection Switching equipment is available in a 2U high chassis which may be mounted in any DIN standard,19-Inch rack.

This product allows the user to design 1+1 (protected) redundant E1 routes on similar (fiber-fiber), or complementing (fiber-radio) transmission mediums.

The criterion for switching between the primary (main) and the secondary (protected / standby) routes is user programmable. Criterion for switching between the primary (main) and the secondary (protected/standby) routes may be Loss-Of-Signal on E1 links, or AIS (All-Ones  AIS alarm) condition. The criterion for switching time and recovery time between the primary (main) and the secondary (protected / standby) routes is user programmable.

Data transported on the E1 Links is transparent and protocol independent.

Features & Highlights

  • High density protection switching equipment (upto 16 E1 Links i.e. 48 E1 Ports)
  • To provide an independent point-to-point, protected E1 Link between two "E1 USER PORTS" on similar (example fiber-fiber), or dissimilar (fiber-radio) mediums
  • To provide 1+1 E1 redundancy support to higher order multiplexers e.g. E2, E3
  • System configuration and management interface through "CLI" text based commands
  • Transport A-bis Interface on redundant E1 links
  • Provide 1+1 Protection Routing / Path between BSC and BTS
  • These ensure that mission critical voice, data, control and management traffic are properly supported and maintained even during E1 backhaul facility outages. When the primary (working) link fails, the E1 traffic is automatically switched to the standby (secondary) link to ensure maximum uptime.
  • Through the comprehensive remote configuration and alarm management capabilities of the VCL-SafeComm, 16 E1, 1+1 Automatic Protection Switching Equipment the product may be used to improve network reliability and control
  • Traffic Protection
  • Alternate Facility Advantages
  • Service Differentiation Agreements
  • Increased Network Reliability Resilience
  • Media and Path Diversity
  • Remote Management
  • Alarm logging and monitoring.
