Hello All, I'm hoping to get some input on which books are good to strengthen my understanding of the telco and their equipment.
Currently I work in the NOC of my company. We primarily do 1st level troubleshooting of our network equipment and T1s. Primarily we have been running point-to-point T1s from our home office our to hub locations which then have small branch offices connect via point-to-point fractional T1s. The design group has started implementing DS3s at the hub locations utilizing ATM back to our home office. The small branch sites now connect to new hub locations via Frame-Relay (the telco is providing us frame-to-atm conversions). Since I'm pretty new to Frame-Relay I'm trying to get a better understanding of exactly what is happening. I understand the basics of Frame-Relay, but I'm looking for a more in-depth discussion of these types of scenarios. A good example is currently we have a site that is bouncing 3/4 times a day. The CSU/DSU on our side shows no errored seconds. The telco is telling me that the DAX (hope that is right for digital cross-connects), is showing no errors. However, they say they are seeing CRC errors, LMI misalignment errors, LMI timeouts, etc., on their Frame-Relay switch. To me, since we aren't seeing errors on their send pair and they aren't seeing errors on our send pair (their DAX with no errors), then the problem exists between their 1st DAX and their Frame-Relay switch. Now, I could be completely wrong and that is why I'm looking for more information - especially since I believe we will be seeing much more of these types of implementations at my organization. So, any books/sites/etc. that you could recommend for me to educate myself on telco inner working and/or DS3/ATM troubleshooting, explanations, etc. would be greatly appreciated. I currently have no books referencing any of these technologies (except for the Larscom CSU/DSU manuals - which aren't too bad - and a ton of Cisco books geared more toward routing/switching/security). I googled for a couple of hours tonight w/out much luck. I also found about 20 books on Amazon, but I'm not sure if they really address my needs. So, again any input sincerely appreciated. Jeff P.S. I just wanted to thank everyone on this list - I've been a lurker for a couple of years and have learned tons form you folks! Got my CCNP and now working toward my CCIE.
