I need to know what LC=down CA=down TM=down LB=down TA=up LA=down stand for. They show up at the botton of a sho int hssi out put
sh int h5/1/0
Hssi5/1/0 is down, line protocol is down
Hardware is HSSI
MTU 1500 bytes, BW 45045 Kbit, DLY 200 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation FRAME-RELAY IETF, crc 16, loopback not set
Keepalive set (10 sec)
LMI enq sent 0, LMI stat recvd 0, LMI upd recvd 0, DTE LMI down
LMI enq recvd 0, LMI stat sent 0, LMI upd sent 0
LMI DLCI 1023 LMI type is CISCO frame relay DTE
Broadcast queue 0/256, broadcasts sent/dropped 0/0, interface broadcasts 0
Last input never, output never, output hang never
Last clearing of "show interface" counters 1w3d
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0
Queueing strategy: fifo
Output queue: 0/40 (size/max)
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
0 packets input, 0 bytes, 0 no buffer
Received 0 broadcasts (0 IP multicast)
0 runts, 0 giants, 0 throttles
0 parity
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
0 packets output, 0 bytes, 0 underruns
0 output errors, 0 applique, 31172 interface resets
0 output buffer failures, 0 output buffers swapped out
0 carrier transitions
LC=down CA=down TM=down LB=down TA=up LA=down

These refer to the signal asserted on specific pins on the HSSI interface IIRC...
LC = Loopback C
CA = DCE Available
TM = Test Mode
LB = Loopback B
TA = DTE Available
LA - Loopback A
TA is asserted outbound. Makes sense for this to be up even though the interface is down.

Hi there. I used the instructions of this cisco document - Document ID: 14197 Back-to-Back Router HSSI Interfaces - to connect the two 7204 routers, but I couldn't get the interfaces to go UP/UP after many tries. Please advise.
