The M7i, M10i, and M40e routers support 12-port T1/E1 PICs, primarily used for wireless backhaul applications. The 12-port PIC can be configured for either 12 T1 or 12 E1 interfaces, but not a combination of both interface types.
To configure support for 12-port T1/E1 PICs, include the framing t1 or framing e1 statements respectively at the [edit chassis fpc slot-number pic slot-number hierarchy level:
- [edit chassis fpc fpc-slot-number pic pic-slot-number]
- framing (t1 | e1);
When the PIC comes online, 12 CT1 or CE1 interfaces are created depending on the interface type (T1 or E1) you include in the framing statement.
To configure the T1 or E1 interfaces, include the interface-type t1 statement at the [edit interfaces ct1-fpc/pic/port no-partition] hierarchy level or the interface-type ce1 statement at the [edit interfaces ce1-fpc/pic/port no-partition] hierarchy level.
To view a list of 12-port T1/E1 PICs, issue the show chassis hardware command. To view the details of a specific PIC, issue the show chassis pic fpc-slot slot-number pic-slot slot-number command.
For further information about configuring the CT1 and CE1 interfaces, see the JUNOS Network Interfaces Configuration Guide
