Might be easier to setup a channel-bank with a bunch of FXO ports to<br>
terminate the analog lines into a T1 and feed the T1 back to the 2921 for<br>
the gateway function. Something like an ADIT 600 or the appropriate Adtran TSU,<br>
and the stock VWIC T1 card on the 2921 rather than mess with all those cards.<br>
<br>
And at the prices the LEC's charge around here for 1FBs vs. PRIs,<br>
switching to a PRI directly would probably pay the NRC and CPE charges<br>
in less than 6 months when you are talking 23 1FBs.<o:p></o:p></p>
