Configuring the 2-Port and 4-Port Channelized T3 SPAs
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:
Command
Router# configure terminal
Router(config)# interface serial slot/subslot/port
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.
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.

Optional Configurations
Purpose
Enters global configuration mode.
Selects the interface to configure and enters interface
configuration mode.
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).
