ISDN Switch Types
The following table summarizes the different types of switches
supported by the DI-300 and DI-300M, as well as some related
information on the switch types (number of phone numbers and
SPID numbers). It should be noted that the information in this table
is for the common case and is recommended for those cases.
Exceptions still exist to these figures. You can locate the
provisioning information for the appropriate North American
switch type in the next sections.

Provisioning For U.S. Switches
For the U.S., the DI-300 and DI-300M (both the U and S/T
interface) have been approved by Bellcore and have the IOC (ISDN
Ordering Code) "S" Capability, EZ-ISDN 1. Provide this
information to your telephone company when you order your ISDN
line. If your telephone company is not familiar with this IOC, then
ask them what kind of switch you will be connected to and use the
information under each switch type to order your ISDN line.
