J3 (previously 'Generic Data J-1DN')
This ISDN ordering code supports:
• 2B
Service,
• alternate voice and data on one B, data only on other B channel, and
• One directory number.
J3 is not available on the Northern Telecom switch. Since two directory numbers are required for 2B
operation, use J2.
Capability S (previously 'Generic Data M')
This ISDN ordering code is the recommended IOC since it supports the most features for voice and data
applications. However, ISDN tariffs in some areas may warrant ordering codes with fewer features (e.g.,
where there is an additional monthly charge for having voice service on both B channels). If yours is a
data only application, you may find Capability R more cost-effective.
Capability S supports:
• 2B
Service,
• alternating voice/data on each B channel, and
• Two directory numbers.
Applications for Capability S include:
•
115.2K or 128K bps data,
• 56K/64K bps data with voice or modem support, and
• Generic 1 15.2K/1 28K bps data transfer applications (including remote access and LAN/WAN
connectivity and telecommuting).
M5 (previously 'Generic Data M-1DN')
This ISDN ordering code supports:
• 2B Service,
• alternate voice/data on each B channel, and
• One directory number.
M5 is not available for services provided with Northern Telecom or AT&T switches. Since two directory
numbers are required for 2B operation, use Capability S.
