4 x DS3/E3 Trunk/Access Module
The 4 x DS3/E3 combined Trunk and Access Module can be configured to either act as a DS3/E3 trunk module, or a DS3/E3 access module. The trunk mode offers four 45 or 34 Mbps interfaces for transporting data with 100% Quality of Service. It enables multi-service operation with guaranteed QoS and high utilization over standard DS3/E3 connections or leased lines. In the Access mode, the module supports all the standard functions of the Nimbra platform, including multicast, fault and performance monitoring and fast 1+1 protection switching.
