140 MultiModemISI Hybrid Series, ISIHI-2S
Appendix
Capability R (previously Generic Data I)
• 2B service
• Data only on each B channel
• Two directory numbers
Applications include:
• 115.2K or 128 Kbps data only (no voice capability)
• Generic 115.2K/128 Kbps data transfer applications (including remote access and
LAN/WAN connectivity and telecommuting)
I2 (previously Generic Data I-1DN)
• 2B service
• Data only on each B channel
• One directory number
Not available on the Northern Telecom switch. Two directory numbers are required for 2B
operation. In this case use J2.
J2 (previously Generic Data J)
• 2B service
• Alternate voice and data on one B channel; data only on other B channel
• Two directory numbers
J3 (previously Generic Data J-1DN)
• 2B Service
• Alternate voice and data on one B; data only on other B channel
• One directory number
Not available on the Northern Telecom switch. Since two directory numbers are required
for 2B operation, use J2.
Capability S (previously Generic Data M)
• 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, Capability R may
be more cost-effective.
• 2B service
• Alternating voice/data on each B channel
• Two directory numbers
Applications for Capability S include:
• 115.2K or 128 Kbps data
• 56K/64K bps data with voice or modem support
• Generic 115.2K/128 Kbps data transfer applications (including remote access and
LAN/WAN connectivity and telecommuting).
