Document Revision 4C Electra Elite IPK II
2 - 658 K-CCIS – IP with IAD

This feature allows Point-to-Multipoint, peer-to-peer connections for calls through the IP
K-CCIS Network. If a call is transferred or forwarded to a different system in the Network,
the trunks in the transferring system are released and a new Point-to-Point connection is
established.

When a call terminates back to the originating system due to call forwarding or transfer, the
intermediate trunks are not released until the call is completed by an answer at the called
party or until the call is forwarded to a different system (similar to the link-reconnect function
in TDM CCIS).

The CCH(4)-U10 ETU is not required to support this feature. It can be installed and used in
a system using traditional K-CCIS with point-to-point T1 lines allowing both IP (K-CCIS) to
NEAX (Point-to-Multipoint) and traditional K-CCIS to be used with the same system.

The LAN connection is provided by a 10 Base-T/100 Base-TX, Auto sensing, full duplex
Ethernet.

The Centralized E911 (K-CCIS) feature is not supported with IP (K-CCIS) to NEAX
(Point-to-Multipoint). Each Electra Elite IPK system in the network must have at least one
local trunk for Emergency 911 calls.

The Electra Elite IPK can send billing information to a billing center office (NEAX2000/
2400), but cannot receive the billing information as the billing center office.

Voice Calls (K-CCIS), voice announce is not supported for a forwarded call across IP
(K-CCIS) to NEAX (Point-to-Multipoint).

This feature is not available when using 6- or 7-digit station numbers.

This feature and the IP (K-CCIS) feature are not supported in the same network.

Not all data networks can support Voice over Internet Protocol (VoIP). A good VoIP solution
requires a low-latency, low jitter, and low packet loss network. Accordingly a network must
be evaluated for latency, packet loss, and jitter to qualify and determine if it can provide toll-
quality speech paths.

With Version 1600 or higher, a remote K-CCIS user can call, or transfer a call directly to an
ACD Pilot number. However, an incoming K-CCIS call to the ACD Pilot number does NOT
provide a Link Reconnect.

When the system searches the Dial Extension Analyze Table (PRG 11-20-01), the system
uses prefix searching, giving the lower table number the higher priority. For example, the
user programs 211 in table 1 and 2113 in table 2, then dials 2113, the system selects table
1.

Program 11-01-01 9: System Numbering – Dial Extension Analyze is not supported in
Version 1600 .

Program 11-20-01: Dial Extension Analyze Table – Dial and Program 11-20-02: Dial
Extension Analyze Table – Type of Dials are not supported in
Version 1600 .
