M5 Line Provisioning--ISDN Ordering Codes (IOC)--(previously 'Generic Data M_1DN')

ISDN ordering codes (IOC) allow customers to order, via a simple code, pre-configured packages of ISDN features and services.

M5 supports:
-2B service,
-Alternate voice/data on each B channel,
-One directory number.

M5 is not available for serviced provided with Northern Telecom (DMS-100) or AT&T (5ESS) switches. Since two directory numbers are required for 2B operation, use Capability S.
