System Overview
IP Key Expansion Module I24
The I24 Key Expansion Module (KEM) expands the IP portfolio by providing more line and
feature appearances for IP sets.
The I24 KEM is ideal for Secretary and Health care. Global markets
BCM50 voice prompts, which were introduced in BCM 4.0, include Polish, Finnish, Korean,
Turkish, and Czech.
The following additional capabilities are available:
• addition of second dial tone for PRI/BRI
— In some markets, a PBX must provide a local tone to the originating party (as opposed
to the central office).
— This feature adds the ability to provide the local tone.
• increased public received digit length from 7 to 12 digits
— Some markets require more than public received digits to support dial plans.
BCM50 1.0 regional bundles for APAC and EMEA are updated to include the GATI or BRI
keycodes in place of expansion chassis and BRI MBM where applicable.
SRG50 Global Bundles are maintained and updated. SRG50 2.0 leverages any geographic
localization enhancements of BCM50.
Localization is a key goal for BCM50. Onboard Analog and BRI trunk profiles are localized to
new markets to offer an integrated solution without dependency on external MBMs for smaller
sites. This solution offers simplicity in installation, improved margins, and a competitive offer in
global regions.
