8 T1 and 16 T1 over Ethernet Multiplexer - (TDM Over IP / TDMoIP)
solution
Valiant's 8T1 and 16T1 over Ethernet
multiplexer (TDM over IP / TDMoIP) product is used to provides 8T1 or 16T1 communication
channels over Ethernet or IP networks. This product transmits information at T1
(1.544Mbps). The equipment supports point-to-point and point-to-multi-point applications.
To transport T1 channels over an Ethernet or an IP network and to accelerate traditional
telecom services to migrate to the IP packet networking technology, the VCL-8/16T1 over
Ethernet multiplexer product uses TDM over IP technology. This solution transports the
legacy T1 data through the existing Ethernet or IP network.
The VCL-8/16T1 over Ethernet multiplexer product is the new generation of the TDM over IP
equipment with IP circuit emulation that supports transportation of upto 8T1 / 16T1 and 5
GE electrical ports over an Ethernet or an IP network. The uplink Ethernet ports and user
data port are IEEE 802.3 compliant, 10/100BaseT auto-sensed ports
T1 - TDM over IP solutions offered are:
Valiant also offer its E1 over ethernet (TDMoIP), ethernet
over E1 converters, ethernet over DS3, E3 converters and Ethernet over
SDH converters.
The 8/16 x VCL-T1 over Ethernet can be used to emulate
transparent T1 channels over an Ethernet link with an acceptable QoS (Please see the note:
QOS, below), so that a majority of the existing T1 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:
- Provides 8T1 and 16T1 ports (available in 1T1, 2T1, 8T1 and
16T1 versions)
- Supports point-to-point and point-to-multi-point
applications
- Provides 5 GE electrical ports and 1 GE optical ports
- User-friendly web server supported for easy setup and
maintenance, Alarm logs provided
- Supports Ethernet spanning tree protocol which enables work
and protection in ring and mesh topology
- Support SNMP V1/V2 Network Management
- Ethernet built-in layer 2 switch, supports VLAN, complies
with IEEE 802.3x, 802.1P
- Provide two pluggable T1 cards, each card supports 8 T1s
- Stable T1 clock recovery, low jitter and wander
- Low processing delay for T1 channels, high bandwidth usage
efficiency
- PCM frame synchronization protection
- User definable encapsulation packet size for different
applications
- Supports Ethernet encapsulation and UDP/IP protocol
encapsulation
- Supports VLAN settings for T1 service and in-band VLAN
management
- Jitter buffer for packet delay variation (PDV)
- Local Ethernet Port throughput limit assuring T1 QoS
- 100 Ohms balanced T1 port, RJ-45 connector
- Support cascade concatenate for more than 16 T1 ports
- Online upgrade for software
- -48V DC Power supply redundancy.
Application # 1: 8T1 / 16T1 over Ethernet is used to setup 8 or 16 T1 channels
over LAN or IP networks

This configuration guarantees that the T1
channels get higher priority over computer data for maximum QoS.
The most widely used application of 8T1/16T1 x VCL-T1 over Ethernet multiplexer is to set
up point to point wireless T1 links using low cost wireless LAN bridges or Ethernet RPR
fiber links. 8/16 x VCL-T1 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.
