I want to setup a lab where RouterA uses a BRI line to connect to RouterB using a PRI line. RouterA is a 2501 with a Motorola TA Connected to S0. The ISDN Switch is an Adtran Atlas 550 with a PRI card and a quad BRI card. On the PRI side can I terminate the circuit with a regular CSU/DSU set to B8ZS - ESF and program the router to treat it like a PRI line? Do I need a different piece of equipment or a router with a PRI interface to accomplish this? After I get that working I want to have 4 Routers using the BRI lines call into the "main router" using only the PRI? Is this possible? ___________________________________ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
