Hi Ed, The TNT-SL-CT3 is the module you are looking for. As the name implies, it is channelized and breaks down the DS3 into DS2 then DS1 and of course, DS0. Once you install the DS3 modules, say in slot 2, you will then have the total amount of DS1's available to you under that same slot. For example: { shelf-1 slot-2 0 } UP UP t3-card admin> dir t3 21 06/23/2003 15:09:07 { shelf-1 slot-2 0 } CDS3 <= note T3 in {1 2 0) admin> dir t1 195 11/06/2002 14:29:56 { shelf-1 slot-2 1 } T3-T1-1 <= note T1 in {1 2 1} 195 11/09/2002 02:29:08 { shelf-1 slot-2 2 } T3-T1-2 <= note T1 in {1 2 2} 195 11/06/2002 15:30:52 { shelf-1 slot-2 3 } T3-T1-3 <= etc. etc. 195 11/06/2002 15:31:21 { shelf-1 slot-2 4 } T3-T1-4 195 11/06/2002 15:31:36 { shelf-1 slot-2 5 } T3-T1-5 195 11/06/2002 15:31:52 { shelf-1 slot-2 6 } T3-T1-6 195 11/06/2002 15:32:14 { shelf-1 slot-2 7 } T3-T1-7 195 11/06/2002 15:46:27 { shelf-1 slot-2 8 } T3-T1-8 195 11/06/2002 15:39:20 { shelf-1 slot-2 9 } T3-T1-9 . . . . After that breakdown, you would then have to configure the PtP based on nailed group, etc. under the 'virtual' T1's line/channel settings. Then, call that nailed group # in your connection profile for each PtP connection. You will also need HDLC modules/resources for PPP over T1's... one HDLC resource for every nailed channel. You cannot nail more than 32 channels in one nailed-group. HTH, David Pascarella CCNP MCSE LCTE Network Support Engineer SOLUNET TAC 1571 Robert J.

I'm not very familiar with the MAX TNT. I need to terminate pt-to-pt T1s, and the telco gives a discount if terminated into a DS3. Can I access the T1s inside the DS3 just like I would with the 8-port T1 board? If so, which TNT part no do I need?
