TN2305
The TN2305 provides an ATM-based replacement for the TN570B/C expansion interface. This interface uses OC-3c or STM-1 155-Mbps multimode fiber. The TN2305 supports both trunk and port-network connectivity. As a trunk, the TN2305 uses Circuit Emulation Service (CES) to emulate up to 8 ISDN-PRI trunks on an ATM facility. As a port-network expansion interface, the TN2305 connects port networks to an ATM switch that provides port network connectivity for an R7r or later network. The TN2305 provides echo cancellation.
The TN2305 does not support hybrid port-networks that use both ATM and CSS simultaneously. TN2305s must connect all port networks through the ATM switch. Direct connect EPNs are not supported.
