 The 2 x VCL-E1 over Ethernet can be
used to emulate transparent E1channels over an Ethernet link with an acceptable QoS
(Please see the note: QOS, below), so that a majority of the existing E1 based
applications can be readily setup over Ethernet LANs and WANs.(Note: QoS shall depend on the quality of the Ethernet link and packet losses)
Features:
- 2 x E1 port supported (available in 1E1, 2E1, 8E1 and 16E1
versions)
- Supports point-to-point and point-to-multi-point
applications
- 2 x Uplink ports : 1+1 backup supported
- User-friendly Web server supported for easy setup and
maintenance
- Support VLAN settings for E1 service and in band VLAN
management
- Support Ethernet encapsulation and UDP/IP protocol
encapsulation
- Jitter buffer to resist packet delay variation (PDV)
- Stable E1 clock recovery, low jitter and wander
- Low processing delay for E1 channels, high bandwidth usage
efficiency
- Resist to packet loss, with PCM frame synchronization
protection
- User definable encapsulation packet size for different
application
- Enough jitter buffer to resist packet delay variation (PDV)
- Local Ethernet port throughput limiting, assuring E1 QoS
- Local and remote E1 LOS and AIS and packet loss indication
for trouble-shooting and maintenance
- Support cascade concatenate for more than 16 E1 ports
.
Application # 1: 2 x E1 over Ethernet is used to setup 2 E1 channel over LAN or IP networks

This configuration guarantees that the E1
channels get higher priority over computer data for maximum QoS.
The most widely used application of 2 x VCL-E1 over Ethernet multiplexer is to set up
point to point wireless E1 links using low cost wireless LAN bridges or Ethernet RPR fiber
links. 2 x VCL-E1 over Ethernet multiplexers can work with most LAN bridges available in
the market. It may be necessary to adjust different parameters such as packet size and
packet jitter absorption buffer size for best operation for different LAN bridges.
