The E3Switch Ethernet to single or dual DS3/E3 switches provide a, typically, zero-configuration method for enabling 100BASETX Ethernet data (or higher) to pass, transparently, over T3 and E3 circuits at up to 87 Mbits/sec true user data rate (dual-DS3). There's no need to worry about VLAN/VoIP issues or packet sizes; the converter makes the T3/E3 circuit appear as a direct, transparent Ethernet end-to-end connection. Dual channel units offer link-aggregation for ordered delivery of packets and automatically determine shortest path for transmission.
E3Switch converters provide several important features that customers will appreciate and which aren't found in competing products. Rigorous attention to design protocols allows users to measure true end-to-end data speed improvements of 2-20% the performance of competing network extenders that rely on HDLC overhead.
Fanless operation and low part-count design allows use with greater reliability and in harsher environments. NEBS Level 3 multicard, redundant-power chassis are available.
Performance upgrade paths exist in all single-channel units, which ship with the capability for the second T3/E3 channel to be activated by password when more bandwidth is required. This is also one of the few products offering a seamless upgrade to jumbo packets and optical SFP as user's GbE technology matures.
Management functions include both comprehensive SNMP statistics with link up/down and DS3 FEAC notifications as well as one-click HTTP, user-friendly, color-coded monitoring of link operational status and bit-error rate. Unique packet auditing display allows individual tracking of every packet from ingress to disposition/egress -- never lose another packet.
Robust frame-lock algorithms maintain link stability and high-BER tolerance on noisy paths such as multi-hop microwave. Link failover protection ensures uninterrupted service if one of the two DS3/E3 paths goes down.
