Telindus Interface Modules offer high-speed WAN or LAN connectivity to the Telindus 16xx and 24xx router family.

WAN interface modules range from E1 (2 Mbps) up to STM1 (155 Mbps). They provide wire-speed router connectivity for network connections based on PPP, Frame-Relay or ATM.

The E1 module comes with 6 physical G.703 connections, supporting either independent or groomed operation. In independent operation mode, each port acts as an individual port on the router, running ATM, Frame-Relay or PPP encapsulation. In combined mode, the bandwidth of different ports is aggregated through IMA (Inverse Multiplexing over ATM), multi-link Frame-Relay or multi-link PPP.

The E3 module supports encapsulation for ATM at 34 Mbps.

The STM1 module features an on-board UTP connector and two-slots for Small Form-factor Pluggable (SFP) fibre-optic transceivers, where the second fibre transceiver module can provide physical backup for the first one.

The LAN interface module provides 4-port Fast Ethernet connectivity.
