TDMoE gateway 32 E1 / T1 / STM / OC - IP6763

Model: IP6763

The Loop-IP6763 transports E1/T1 plus STM-1 signals over an IP network. 

As the core communications network migrates from legacy TDM to Metro Ethernet to leverage CapEx and OpEx efficiently, the Loop-IP6763 TDMoEthernet Aggregator provides a cost-effective solution which allows operators to transport up to 32 E1/T1, 4 STM-1/OC-3 or 1 STM-4/OC-12 along with 4 Giga LAN traffic over existing Metro Ethernet network. The E1/T1 SCSI interface is fixed on main board while there are two hot-swappable tributary slots for STM-1/OC-3 or STM-4/OC-12 plug-in card types.

Loop-IP6763 TDMoEthernet Aggregator converts the TDM data stream and timing information from both PDH and SDH/SONET ports into packets and transmits to the connected Metro Ethernet network via dual combo Gigabit Ethernet WAN ports with 802.3ad Link Aggregation capability. Another Pseudowire device converts the received packet stream back to original PDH and SDH/SONET data stream along with the original timing information.

Loop-IP6763 TDMoEthernet Aggregator employs various Pseudowire Encapsulation protocols such as SAToP, SONET/SDH CEP, CESoPSN, MEF-8. To compensate the inherent Packet Delay Variation (PDV) of Metro Ethernet network, Loop-IP6763 TDMoEthernet Aggregator utilizes Jitter Buffer Control and can compensate up to 128 ms with G.823/G.824 Traffic Interface conformance (+/- 1ppm).

Security is highly ensured via SSHv1/SSHv2 function and SNMPv1/v3 management.
