| VCL-SafeCommTM,
8 T1 Links (24 T1 Ports) (1+1
Automatic Protection Switch)
Product Description
| The VCL-SafeComm, 8
T1
Links (24 T1 Ports), 1+1 Automatic Protection Switching Equipment
may be used to protect upto 8 T1 Links (24 T1 Ports), point-to-point
links and provide an alternate communication route to each T1
Link between any two T1 points. |
 |
|
In the event of the failure of the primary (Main) T1
communication route, the VCL-SafeComm, 8 T1 Links
(1+1 Automatic Protection Switching Equipment) automatically
switches the T1 traffic to a secondary (standby) T1 route. The
VCL-SafeComm, 8 T1, 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 T1 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 T1
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 T1 Links is transparent and
protocol independent.

Features & Highlights
- High density protection switching equipment (upto 8 T1 Links
i.e. 24 T1 Ports)
- To provide an independent point-to-point, protected T1 Link
between two "T1 USER PORTS" on similar (example fiber-fiber), or
dissimilar (fiber-radio) mediums
- To provide 1+1 T1 redundancy
- System configuration and management interface through "CLI"
text based commands
- Transport A-bis Interface on redundant T1 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 T1 backhaul facility outages. When the primary (working)
link fails, the T1 traffic is automatically switched to the
standby (secondary) link to ensure maximum uptime
- Operates on -48 V DC power input. AC power input (optional)
- Through the comprehensive remote configuration and alarm
management capabilities of the VCL-SafeComm, 8 T1, 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.
Benefits
- Customer Relations
- Competitive
- Service Level
- Back-haul Network
- Technology Migration
- User Programmable 1+1 Protection Parameters:
-
Loss of
Signal
-
AIS (All Ones
Alarm)
Applications
Providing 1+1 alternate paths between any two
Transmissions mediums (active+standby). e.g:
- Fiber / Fiber
- Radio / Fiber
- Radio / HDSL
- Fiber / HDSL etc.
