So far:
Wednesday April 19th - 4:00pm to 5:15pm
The image above shows numerous CRC and frame errors as reported by the Adtran units that connect the point-to-point T1. The count is higher on the Bronx side (right side of the image). I cleared all of these stats when I was last logged on a week and half to two weeks ago so I am sure they have all occurred since then. I cleared them again yesterday. After clearing the statistics, I started a file download from a desktop in the Bronx the to a desktop I was logged into in Manhattan and while the download was taking place, asked ESS to place a call to the Bronx. Unfortunatly, the counters did not increment as quickly as I expected. There was only one CRC and one Frame error on the Bronx side. However, this is still an indication that there are line problems.
I checked the configurations on the NEC systems and the Adtran units and they are as I left them. I can only verify configurations for the aforementioned equipment since I viewed for accuracy or adjusted the configurations to provide acceptable voice quality the last time this issue was addressed. I cannot say other devices or new devices on ESS's network are not causing a problem. ESS did inform me that Verizon was in thier phone room for two days though it was not disclosed to me what work they were performing. Charles was also at ESS just recently but was there for training and not modifying the configurations of the NEC phone systems.

Adtran makes an excellent product for many networking scenarios. One of the best most recent devices and application I've seen Adtran place a solution for was for a point-to-point network connection with two Adtran Netvanta 3200 series routers at each end. They work great. They have the reliability everyone knows Adtran for and they have some great QoS features that are easy to configure available from a web browser.
The command line is nice too and simulate Cisco's IOS. This fact helps reduce the learning cure that would other wise be required if Adtran had developed their own command line.
