It is VERY unlikely that your local LEC does not offer Frame (if all of
your offices are in the same LATA/RBOC). If not, check WorldCom (aka MFS
aka UU Net aka GTE). They are *very* competitive for (inter)national
frame relay.
And, a suggestion: If running IPX and IP, over multiple PVC's, ditch the
Livingston and look at the Ascend P130 or a good 'ole 2501.
(oops.. Is this the livingston list? I meant, use ALL livingstons).
