Ethernet Over STM1 Converter

Product Overview :

Team Link is a cost-effective and good-performance product that provides 8/16 E1/T1, 2/4 Ds3, 4/8 ports of 10/100 Base T card as tributary, It deliveries various services to the customer premises over STM-1 (155Mbps) optical network.

The Team Link system is the transmission equipment which can provide a flexible and versatile solution to TDM and IP services and use two fiber links for 1+1 auto protection to deliver up to 155Mbps based on customer's application.

Versatile Network Management System :

Team Link provides a functional Craft Interface and easy-to use GUI Network Management. Performance indexes are also available for better monitoring. Easy and
smooth facilities provide powerful operation and maintenance for both remote and central sites.

Scalability in Ethernet Services :

The Ethernet services is scalable to fit in fields requires by administrators from 2 up to 100Mbps (increased by 2.048Mbps or 1.544Mbps) with GFP, VCAT & Link Capacity
Adjustment Scheme LCAS) to adjust in transmission capacity with hitless traffic for user bandwidth requirement.
