"It still does nothing."
"Yes, this is the phone company. May I please speak with Mr. Isdn?"
T
he jokes and stories regarding Integrated Services Digital Networks
(ISDN) have been merciless and, in some cases, more prevalent than the ser-
vice itself.
Although it is true that ISDN is difficult to order and configure, ISDN is
an important option for administrators to consider when designing net-
works. Frame Relay and xDSL are strong contenders, but ISDN's availabil-
ity and cost advantages in certain situations are difficult to ignore. In
addition, the difficulties in configuration have been removed to a large
degree as the service becomes better known.
Some of the commands listed in this chapter are unavailable on certain Cisco
routers because of hardware and software considerations. The Cisco 804
router with internal ISDN BRI was used to provide the screen output for this
chapter.
