These are trunk side T1's, no I noticed that when the TELCO had our T1 set to AMI/D4 that we lost all our diagnostic functions from the 10-400 status window. If you don't have B8ZS and ESF, you do not get the extra stats, and if memory serves correctly you can get 8bit clean connections with AMI/D4. Mat Renner is one of ascends strongest TELCO people their, I'd suggest a call to him.. > What I'm looking for is: > 1- Has anyone with channelized T1 gotten 56k to work on a MAX? On a PM3? We have it working on a MAX 4048 feel free to dial LD to (352) 742-1515. Users are averaging 48K. With channelized T1's we found that Padding with Leading Zero's in the Switch helped our connect rates. Here is a repost of that message. Take Care. From: Dave Van Allen <dave@fast.net> To: 'Kevin Smith' <kevin@ascend.com>, 'Matt Holdrege' <matt@ascend.com> Cc: "'ascend-users@bungi.com'" <ascend-users@bungi.com> Subject: Digital Padding at the Switch, was RE: (ASCEND) 56k and CT1 Just FYI - On channelized T1's (not PRI), the digital-padding Kevin refereed to is usually configurable at the Switch. While I don't have specifics for Lucent/AT&T switches, on NorTel the following info may be handy. When ordering lines (trunk side) from DMS provisioned services, specify to the provider that you wish to have your trunks data-filled with NIL PAD GROUP. This tells the DSP on the DMS switch to *not* alter the gain or frequency response of the incoming DS0 channels. Most Telco's still apply standard "pads" to data circuits incorrectly, mainly because of not understanding the issues. (they use voice designed pads as a default in many cases) On a DMS switch, there are about 50 pad groups, the one you usually want is "NPDGP" (NIL PAD GROUP) In some cases, this change alone is worth 2 speed increases higher in connect rates, and far less "phantom" discos for end users. You mileage will vary and there are a few reasons why this is NOT absolute advise for all instances, but it is a pointer for those who are experiencing troubles.
