one needs to determine if the modulator is a G.Lite, DBIC, POTS, ISDN, x.25 or some other hardware level protocol adapter. As all these terminiating devices have various connectors and cabling schmatics, we must ensure we use the appropriate interlinks. For a simple ISDN, one must ensure the PRI and/or BRI's are functional in tandem and that the modem is connected to the PSTN (from the CO) POTS/ISDN breakout and from there one must use a dual-male CAT3 (not a CAT5X) patch to the WAN router, from there all tables must be defined either using RIP, BGP4, or somehow maybe even MPLS. This is critical otherwise The Packets may go Martian or even get dropped. From there we can use a cable to connect to the computer equipment or LAN using an Xover cable unless one of said devices has an MDI-X interface, in which case that can be use and a 1:1 patch again can be used.
Sound good? No nitpicking please - I've never worked with ISDN before :) |
