ISDN – General Description
ISDN is a dial-up technology. It has to establish, maintain and terminate the circuit via a “Delta” channel. It transmits and receives data via “Bearer” channels. This can be done “in-band” or “out-of-band” depending on standards and equipment. ISDN Technologies are broken down into BRI and PRI. Bearer channels carry the data. Delta channels are [...]
PPP

Configuring an asynchronous dialup connection on Cisco Routers
Objective The objective here is to configure two Cisco routers to connect to each other using PPP. The routers will also be configured to provide in-band connections through the serial interfaces. Then configure the asynchronous connections to support PPP and Dial-On-Demand Routing (DDR). Inventory ROUTER 1 Fa0/0 192.168.0.1/24, S0/1 192.168.8.1/24 MODEM 1 HOST 1 192.168.0.2/24 [...]
