Help!!!!! (Cấu hình PRI trên 2650)

Help

Tôi cấu hình PRI ISDN E1 trên router Cisco 2650 cho tổng đài Siemens Hicom 150E sử dụng QSIG. Những sau khi cấu hình, chạy test thì protocol layer 2 và layer 3 đều up khi gọi vào (nói chung là tốt). Nhưng đến khi nối với tổng đài khi thử gọi vào thì nó lại chập chờn không kết nối được.

Tôi lại phải giải quyết nó gấp do vậy rất mong các bạn quan tâm và giúp đỡ giải quyết tôi.
Xin cảm ơn nhiều! :D

present,

Do bạn cần quá gấp và không post config của bạn lên, nên mình gửi bạn một cấu hình tham khảo.

Trong trường hợp của bạn, post output của các lệnh sau:

#show version

#show run

Còn đây là một cấu hình E1 controllers:

Configuration Example

--------------------------------------------------------------------------------

The following example configures R2 signaling and customizes R2 parameters on controller E1 1/0 of a Cisco 3640. In most cases, the same R2 signaling type is configured on each E1 controller.


--------------------------------------------------------------------------------
Step 1 Enter global configuration mode using the configure terminal command:


Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Step 2 Specify the E1 controller that you want to configure with R2 signaling using the controller e1 slot/port global configuration command. A controller informs the router how to distribute or provision individual timeslots for a connected channelized E1 line. You must configure one E1 controller for each E1 line.

Router(config)# controller e1 1/0
Step 3 Configure channel associated signaling with the cas-group channel timeslots range type signal command. The signaling type forwarded by the connecting telco switch must match the signaling configured on the Cisco 3640. The Cisco IOS configuration options are r2-analog, r2-digital, or r2-pulse.

Router(config-controller)# cas-group 1 timeslots 1-31 type ?
r2-analog R2 ITU Q411
r2-digital R2 ITU Q421
r2-pulse R2 ITU Supplement 7
The following example specifies R2 ITU Q421 digital line signaling (r2-digital). This example also specifies R2 compelled register signaling and provisions the ANI ADDR option.

Router(config-controller)# cas-group 1 timeslots 1-31 type r2-digital r2-compelled ani

Note For a description of the supported R2 signaling options, see the cas-group (controller e1) command reference page. The actual R2 channel associated signaling is configured on the 16th timeslot, which is why the timeslot does not come up in the example output.


--------------------------------------------------------------------------------

Step 4 Customize some of the E1 R2 signaling parameters with the cas-custom channel controller configuration command. This example specifies the default R2 settings for Argentina. See the cas-custom command reference page for a detailed description of these options.

Router(config-controller)# cas-custom 1
Router(config-ctrl-cas)# ?
CAS custom commands:
ani-digits Expected number of ANI digits
answer-signal Answer signal to be used
caller-digits Digits to be collected before requesting CallerID
category Category signal
country Country Name
default Set a command to its defaults
dnis-digits Expected number of DNIS digits
exit Exit from cas custom mode
invert-abcd invert the ABCD bits before tx and after rx
ka KA Signal
kd KD Signal
metering R2 network is sending metering signal
nc-congestion Non Compelled Congestion signal
no Negate a command or set its defaults
request-category DNIS digits to be collected before requesting category
unused-abcd Unused ABCD bit values
Router(config-ctrl-cas)# country ?
argentina Argentina
australia Australia
brazil Brazil
china China
columbia Columbia
----cut----
Router(config-ctrl-cas)# country argentina ?
use-defaults Use Country defaults
<cr>
Router(config-ctrl-cas)# country argentina use-defaults
