Cisco Systems Inc. announced two new channelized interfaces for the Cisco 12000 Gigabit Switch Router (GSR). Cisco's new channelized interfaces support up to 12 digital signal level three (DS3) channels on a single port and four OC-3/STS-3c channels on a single OC-12 port.

Both interfaces permit a single optical connection between the Cisco 12000 GSR and the SONET access network.

The channelized OC-12/DS3 replaces up to 12 copper-based, data service units (DSUs) or channel service units (CSUs), and attaches directly to SONET-compliant Add Drop Multiplexers (ADMs) that enable the Cisco 12000 to transmit and receive DS3-based, IP packets across a standard SONET network.

The channelized OC-12/STS-3c allows service providers to offer up to four 155-Mbps connections on a single optical interface. This interface is also designed to interoperate with existing SONET transmission equipment.

Cisco's new channelized interfaces also support frame relay encapsulation of IP packets.
