## (7) ISDN Implementation

### ServiceCenter Router - ISDN Configuration

Router(config)# isdn switch-type switch type Router(config)# interface bri interface-number Router(config-if)# encapsulation ppp Router(config-if)# isdn spid1 spid-number [idn] Router(config-if)# isdn spid2 spid-number [idn]

Note: The other two regional Hub routers will be set up the same way

### ISDN Implementation

The community school will have an IDSN connection into the Washington District WAN, allowing 128Kbps of bandwidth for data. The school will have computers (T1 devices), phones (T2 devices), adaptors for the phones (TA's) and one NT1 and NT2 device for connection to the four-wire network.

### Benefits of ISDN implementation

- Community School has only a small number of users, so 128K is sufficient bandwidth
- ISDN can carry voice, data and video
- ISDN can setup a call in less than 1 second
- ISDN has a faster tranfer rate

### Management Commands
