3.5.3.
ISDN provisioning with IOCs
ISDN service may be ordered using ISDN Ordering Codes (IOCs) or capability packages. If
the local telephone company supports IOCs, the instructions in this section are applicable. For
the purposes of ordering ISDN lines, capability package designations and IOC codes are
equivalent. Therefore, ordering capability package (IOC) U or EZ-ISDN 1 is equivalent.
The development of ISDN ordering codes (IOCs) simplifies the process of ordering ISDN
service. The ISDN Solutions Group, a consortium of ISDN equipment vendors, service
providers, and Bellcore, established these codes to represent predetermined line
configurations for ISDN Basic Rate service for specific applications. If the local service
provider does not support IOCs, see the section
ISDN Provisioning without IOCs
.
3.5.3.1.
EZ-ISDN 1 (capability package U)
Ordering EZ-ISDN 1 (Capability Package U) is recommended by the industry for most small
office/small business applications. EZ-ISDN 1 or EZ-1 provides a voice and data BRI line
with a set of supplementary voice features enabled. If EZ-ISDN 1 is not available from the
local service provider, consider the remaining options listed in this document.
Note:
For the purposes of ordering the ISDN line, IOC U and EZ-ISDN 1 differ from IOC
V and EZ-ISDN 1A only in that the latter include support for voice mail. If voice mail
is needed, IOC V or EZ-ISDN 1A should be chosen. In all other respects, the two are
identical. The general and supplementary voice features associated with EZ-ISDN 1
are listed below:
3.5.3.1.1.
Features
•
2B service
•
Both B channels alternating voice and data
•
Two directory numbers
•
Flexible calling voice features (call forwarding, call transfer, call waiting,
three-way conference calling)
•
Caller ID
Automatic support for call waiting, call conferencing, call transfer and call forwarding applies
only to the first telephone or Directory Number provided (also called Directory Number 1).
For IOC V and EZ-ISDN 1A, voice mail support is automatically included only for the first
DN. Caller ID is supported on both Directory Numbers 1 and 2, but not on the secondary
Directory Numbers (if any). Therefore, if the supplementary voice features are required on the
second or other Directory Numbers, they must be specifically requested.
•
For Call Waiting (as well as Dynamic Bandwidth Allocation) ask for
Additional Call Offering (ACO)
•
For Call Conference (Three-Way Calling) and Call Transfer, ask for
Flexible Call Offering (FCO)
•
For Call Forwarding, ask for Call Forwarding Variable
•
For Voice Mail (if ordering IOC V or EZ-ISDN 1A), ask for Voice Mail
