Can't speak for all, but every T1 NIU I've seen has been powered from central office battery over the same pair(s) that deliver the T1 signal. So, ability to loop the NIU verifies that the telco span to the premise and the NIU itself are working. If the NIU loops up and the CSU doesn't, then the most likely issues are local utility power or inside wiring. If neither loops, it's most likely a trouble with the telco pair(s) between the CO and the NIU, aka backhoe fade. -- Jay Hennigan - CCIE #7880 - Network Engineering - j...@impulse.net Impulse Internet Service - http://www.impulse.net/ Your local telephone and internet company - 805 884-6323 - WB6RDV ___ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/

Re: [c-nsp] Looping up far end smartjack
I just thought about that for a second.. If the T1 is down then the router will be down as well. In the event of a power outage I still can't tell if the power is off or the T1 is down.If I can hit the smart jack and not the router then I could assume it's a power outage.

The router doesn't even need to be connected. CSUs that are integrated into a WIC will probably not respond if the router is in rommon, although I haven't tried it. I believe that some microcode needs to load from IOS to make the WIC functional. Old-school external CSUs like the Adtran TSU will loop regardless of the state of the router. -- Jay Hennigan - CCIE #7880 - Network Engineering - j...@impulse.net Impulse Internet Service - http://www.impulse.net/ Your local telephone and internet company - 805 884-6323 - WB6RDV ___ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/

Richey Richey, I believe the remote T1 loopback features are only for CSU/DSU. The trouble comes when you want to loop it back down - it seems that the software in the router does not have the right loop-down codes. I have successfully looped up a remote CSU/DSU but have never been able to drop it without access to the CSU/DSU that I looped and manually clearing it (or inserting a T-BIRD and sending the right loop-down code). If anyone else has experience in getting this to work, I would be interested to hear.

The fortunately for Richey, this is incorrect. to drop it without access to the CSU/DSU that I looped and manually clearing it (or inserting a T-BIRD and sending the right loop-down code). If anyone else has experience in getting this to work, I would be interested to hear. I suppose this can become a NIU/smartjack specific question. As far as I am aware, Cisco will send the proper bits in the FDL towards the, sending first the loopback enable command (which are stuffed into the 4kbit/sec FDL portion of the ESF header -- the other 4kbit of course are ESF CRC bits), and then sending loopback disable when the command is removed. This has worked fine in practice over several lec and clec TDM networks. The commands that work for pa-mc-t3 and ct3-ip (yes, vip+7500 rocking out in 2010 = awesome) are: (config-if)#loopback remote line fdl ? ansi Per ANSI T1.403 Spec. (remote CSU) bellcore Per TR-TSY-000312 Spec. (remote SmartJack) I have found the cisco mft-t1 VWIC's will respond to CSU loopback commands, and nearly every single ADC, adtran, etc NIU has worked fine given bellcore FDL loopback commands. Of course, I have also noticed anywhere from a 15 to 20 minute 'forced loopback timeout' -- so doing extended tests can be confounded by 'blips' where the smartjack will auto-disable its loopback state. -Tk ___ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
