RE: csu-dsu [7:11233]
Did you specify the clock source? service-module t1 clock source internal service-module t1 clock source line where internal uses the adapters internal clock and line gets the clocking from your service provider.

Providing a T1 conectivity netween two of our sites. We are going to be using a 2600 for this same connection .The 2600 has a built in CSU/DSU. My problem is I do not get a coneectivity between the two sites when I use the 2600. I know the card works as I tested it with another T1 conection. No problem. the carrier is using SF Framing , linecode AMI . the encapsulation is HDLC. the 7500 with the external CSU/DSU works fine. however with the 2600 I keep on seeing Serial up , line down. I know on our existing 2600 with built in csu/dsu I have chanel-group 0 , time slot1-24 and speed 64 configured on the controllers. one thing I noticed on the 7500 csu/dsu it was set up with clk_master : LBT .is this specific to the carrier ? is there something im missing on my configs. The route statementsconfigured on teh 2600 are exactly the same as the 7500 , so there is no routing issue.

Will the NM-4T work on 2600 series routers [7:3056]
It seems that there is some confusion wrt network modules and 2600/3600 routers. Searching on Ciscos site, they say that the NM-4T is not supported for the 2600 series but I see cisco resellers, and others advertising the NM-4T for 2600/3600 routers. Am I missing the doc from Cisco that says the NM-4T is now supported on the 2600 sereis? Can anyone provide some imput. Thanks. -Joshua Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=3056t=3056 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

RE: difficult ccna question
Based on the subnet mask (255.255.192.0) subtract 256 from 192 which is 64. Therefore 64 is your first subnet. To get the second subnet, add 64 to the first subnet. To get the third add 64 to the second subnet and so on. Continue in this fashion until you reach 192. Remember that you cannot use the ranges 172.16.0.1 - 172.16.0.62 and 172.16.255.193 - 172.16.255.254 (network and broadcast respectively) unless your router is configured to do so.

RE: difficult ccna question
Technically yes. But like most things you cannot get something for free. There is a price for subnetting which is that you loose the first subnet (network - all zeros) and the last subnet (broadcast - all ones). Note that with some routers you can configure them to use these subnets. But be careful, because some OS's and devices do not react well to using then. HTH. -Joshua -Original Message- From: David A.
