Cisco Lab - Page 3

post #21 of 25
Did you also do commands such as:

service-module t1 clock source internal (use service-module t1 clock source line on the other router)
service-module t1 timeslots 1-24 speed 64
service-module t1 framing esf
service-module t1 linecode b8zs

?

Also, to have a more 'labby' environment you can give your pair of serial interfaces a /30 address.
Assign one to 10.1.1.1 and the other to 10.1.1.2 with a mask of 255.255.255.252.

Usually when you get a T1 from a provider you'll be given an address from a /30 pool with the other assignable address in the subnet going to the provider edge equipment.

I set this environment up in my hardware lab to see if it would alleviate any of your frustrations smile.gif
The alarm light went out after putting in 'service-module t1 clock source internal' on one side and having both interfaces enabled.

I made a T1 cable using this pinout:


Code:
R1-3660#show run int s1/0
Building configuration...

Current configuration : 173 bytes
!
interface Serial1/0
 ip address 10.0.0.1 255.255.255.252
 encapsulation ppp
 no fair-queue
 service-module t1 clock source internal
 service-module t1 timeslots 1-24
end
Code:
R2-2651XM#show run int s0/2
Building configuration...

Current configuration : 117 bytes
!
interface Serial0/2
 ip address 10.0.0.2 255.255.255.252
 encapsulation ppp
 service-module t1 timeslots 1-24
end

Ping replies (Click to show)
Code:
R1-3660#ping 10.0.0.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.0.0.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/3/4 ms


R2-2651XM#ping 10.0.0.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.0.0.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms

Does this help at all, even though this lab assumes you are using T1 WICs?
