Optima's T:LAN NetStream Series high speed network access units provide you with a cost-effective and highly reliable solution for remote LAN connectivity.

T:LAN units are the ideal tool for Virtual Private Networking, LAN extensions, or high speed Internet access. Bridging the gap between a single T1/E1 and costly T3/E3 access, the T:LAN NetStream bonds the bandwidth of two T1/E1 circuits to provide upwards of 3Mbit/s (T1) or 4Mbit/s (E1) of symmetrical throughput, transparently via TDM, IP or Frame Relay/ATM based backbones.

Each T:LAN unit comes ready to go out of the box. Unpack, wall or rack-mount and connect your T1/E1 links! LAN service delivery has never been easier.
