Does anybody know any alternatives to the TxPort 1558 Auto Protection switch? This box allows switching from one PRI to another in case one of them goes down. Conversely, it allows switching a single PRI going to one PBX (or * box) to another in case the PBX goes down. Does AdTran make such a box? What about multiple PRI failover devices? -- ____________________________________________________________ Muiz Motani Intelligent Distribution 72-6800 Lynas Lane, Richmond, B.C.
