WIC-56/64K-CSU/DSU和NM-1CE1T1-PRI背靠背线缆及配置

天对WIC-56/64K-CSU/DSU和WIC-56/64K-CSU/DSU进行了背靠背的线缆连接及配置。
过程如下(下面简称为56K和T1):
首先确认56K的线缆连接方式:
A:12345678
B:78345612
其中A端:
1:tx ring
2:tx tip
7:rx tip
8:rx ring
B端:
7:rx ring
8:rx tip
1:tx tip
2:tx ring
说白了就是吧12以及78对换。
线嘛,RJ45或者RJ48都可以。
插上去以后两端做如下动作:
interface serial 0/0
service.module 56k clock rate 56
service.module 56k clock source internal
ip address 10.1.1.1 255.255.255.0
encapsulation ppp
no shut
IP地址注意自己改一下,然后看到tx和rx都起来了,cd也起来了,ping一下,通了!
顺便解释一下灯的含义:
TD Data is being transmitted to the Data Terminal
Equipment (DTE) interface.
RD Data is being received from the DTE interface.
LP The internal DSU/CSU is in loopback mode. Solid
illumination any time a loopback is active.
AL One of these alarm conditions is present: no receive
signal, loss of frame signal from the remote station, or
out of service signal from the remote station. This LED
is off during normal operation.
CD The internal DSU/CSU in the WAN interface card is
communicating with another DSU/CSU.
show一下接口的情况:

Serial0/0 is up, line protocol is up
Hardware is GT96K with 56k 4-wire CSU/DSU
Internet address is 10.1.1.1/24
MTU 1500 bytes, BW 56 Kbit, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation PPP, LCP Open
Open: CDPCP, IPCP, loopback not set
Keepalive set (10 sec)
Last input 00:00:01, output 00:00:01, output hang never
Last clearing of "show interface" counters 02:01:00
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0
Queueing strategy: weighted fair
Output queue: 0/1000/64/0 (size/max total/threshold/drops)
Conversations 0/1/16 (active/max active/max total)
Reserved Conversations 0/0 (allocated/max allocated)
Available Bandwidth 42 kilobits/sec
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
1309 packets input, 60544 bytes, 0 no buffer
Received 0 broadcasts, 0 runts, 0 giants, 0 throttles
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
1309 packets output, 59773 bytes, 0 underruns
0 output errors, 0 collisions, 1 interface resets
0 output buffer failures, 0 output buffers swapped out
2 carrier transitions
DCD=up DSR=up DTR=up RTS=up CTS=up
搞定。

下面来看看t1怎么弄:
线缆:
A端:12345678
B端:45312678
其中A端:
1:rx(in)
2:rx(in)
4:tx(out)
5:tx(out)
B端:
4:tx(in)
5:tx(in)
1:rx(out)
2:rx(out)
这样就做好了,插上去,一开始是不会亮的。
接下来我们按照T1的标准配:
1. enable
2. configure terminal
3. card type t1 slot
4. controller t1 slot/port
5. linecode {ami | b8zs}
6. framing {sf | esf}
7. clock source {line | internal}
8. pri-group [timeslots range]
9. exit
10. copy running-config startup-config
然后show一下controller:
T1 1/0 is up.
Applique type is Channelized T1
Cablelength is long gain36 0db
No alarms detected.
alarm-trigger is not set
Framing is ESF, Line Code is B8ZS, Clock Source is Line.
Module type is Channelized E1/T1 PRI
Version info Firmware: 0000001D, FPGA: 0
Hardware revision is 0.0 , Software revision is 29
Protocol revision is 1
number of CLI resets is 0
receive remote alarm : 1,
transmit remote alarm : 0,
receive AIS alarm : 0,
transmit AIS alarm : 0,
loss of frame : 1,
loss of signal : 0,
Loopback test : 0,
transmit AIS in TS 16 : 0,
receive LOMF alarm : 0,
transmit LOMF alarm : 0,
MIB data updated every 10 seconds.
Data in current interval (513 seconds elapsed):
0 Line Code Violations, 0 Path Code Violations
0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins
0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs
Total Data (last 6 15 minute intervals):
0 Line Code Violations, 7 Path Code Violations,
0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins,
0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 50 Unavail Secs
看灯好像也都是正常的,亮了T1和cd,不知道是不是这样就行了,吼吼~
有些地方还没弄懂,慢慢了解吧。
