Example: Configuring Channelized STM1 Interfaces
The following configuration is sufficient to get the Channelized STM1-to-E1 PIC interface up and running. The channelized STM1-to-E1 interface is an STM1 that is divided into 63 E1 interfaces. E1 interfaces can use the following encapsulation types:
PPP, PPP CCC, and PPP TCC
Frame Relay, Frame Relay CCC, and Frame Relay TCC
Cisco HDLC, Cisco HDLC CCC, and Cisco HDLC TCC
The channels can also have logical interfaces. For information about Frame Relay DLCI limitations for channelized interfaces, see Data-Link Connection Identifiers on Channelized Interfaces. For more information about Frame Relay DLCIs, see Configuring Frame Relay DLCIs. For more information about DLCI sparse mode, see the Junos OS Administration Library.
You apply all STM1 interface SONET/SDH options to the first E1 interface in the configuration by including the sonet-options statement at the [edit interfaces e1-fpc/pic/port:channel] hierarchy level:
