Cisco ASR 1000 Series Software Configuration Guide

Verifying Encapsulation
Use the show interfaces serial command to display the encapsulation method:
Router# show interfaces serial2/0/0
Serial3/0/0 is down, line protocol is down
Hardware is SPA-2XCT3/DS0
MTU 4470 bytes, BW 44210 Kbit, DLY 200 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation HDLC, crc 16, loopback not set
Keepalive set (10 sec)
Last input never, output never, output hang never
Last clearing of "show interface" counters never
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, 2 interface resets
0 output buffer failures, 0 output buffers swapped out
1 carrier transitions alarm present
DSU mode 0, bandwidth 44210 Kbit, scramble 0, VC 0
Configuring T3 Framing
To set the T3 framing type, use the following commands:
PurposeCommand
Enters global configuration mode.Router# configure terminal
Selects the interface to configure and enters interface
configuration mode.
Router(config)# interface serial slot/subslot/port
Specifies the framing type in unchannelized mode.
• c-bit—Specifies C-bit parity framing. This is
the default.
• m13—Specifies DS3 Framing M13 (same as
M23).
Router(config-if)# framing {c-bit | m13}
Verifying Framing
Use the show controller command to display the framing type:
Router# show controller t3 3/0/0
T3 3/0/0 is down. Hardware is 2 ports CT3 SPA
ATLAS FPGA version: 0, FREEDM336 version: 0
TEMUX84(1) version: 0, TEMUX84(1) version: 0
SUBRATE FPGA version: 0
Applique type is Subrate T3
Receiver has loss of signal.
