dialer load-threshold requires the ppp multilink command to be configured, and the value of dialer load-threshold is expressed as a ratio of 255, NOT 100. For example, if you want the second b-channel to come up when the first reaches 50% of capacity, the value to express with dialer load-threshold would be 50% of 255 – which equals 127.

The Cisco-proprietary version of HDLC is the default encapsulation type for serial and ISDN interfaces.
R2#show interface serial0
Serial0 is up, line protocol is up
Hardware is HD64570
MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec, rely 255/255, load 1/255
Encapsulation HDLC, loopback not set, keepalive set (10 sec)
While there’s only one D-channel in BRI, PRI (US) and PRI (EU), the bandwidth of that D-channel does vary from BRI to PRI. It’s 16 kbps in BRI and 64 kbps in both PRI versions.
The global command isdn switch-type must be configured before you can even begin to have ISDN work. show isdn status will tell you whether or not you’ve done this correctly.
