Hi,
I have a CESoPSN terminated on a T1 port 0/2/1, See below for configuration.
controller T1 0/2/1
linecode b8zs
cablelength long 0db
cem-group 0 timeslots 1-24
interface CEM0/2/1
no ip address
cem 0
xconnect 10.221.221.87 100 encapsulation mpls
SYS22-Cis#show xconnect all
Legend: XC ST=Xconnect State, S1=Segment1 State, S2=Segment2 State
UP=Up, DN=Down, AD=Admin Down, IA=Inactive, NH=No Hardware
XC ST Segment 1 S1 Segment 2 S2
------+---------------------------------+--+---------------------------------+--
UP ac CE0/2/1(CESoPSN Basic) UP mpls 10.221.221.87:100 UP
For testing purposes, I wanted to put a loopback cable in the T1 port, so that traffic is looped back over MPLS to the source. However, when I create the loopback cable as shown below, the port does not go green? The document for the VWIC 2T1/E1 card, specifies that the port must use RJ-48C.
Below is my loopback cable. Is this correct?
Pinout:
PIN1: RX Ring <-------\
PIN2: RX Tip <*******|***
PIN3: Reserved | *
PIN4: TX Ring >-------/ *
PIN5: TX Tip >***********
PIN6: Reserved
PIN7: shield
PIN8: Shield
Also, the port is showing that it is UP, with no cable in it. How is this possible?
