1. SIM SERVER Central SIM storage & management Full integration with DTT products Easy user defined SIM management rules Ability to change Time & IMEI Simultaneously via IP for each SIM As the SIM cards are remotely located, GSM gateways, SIM management becomes quick, easy and secured. SIM cards are no longer permanently attached to a given GSM port or a given GSM Multi-Cell Gateway. Protection for IP network failure Modularity: 32 SIMs per card via local BUS or via IP –1U: 32 to 192 SIMS –3U: 32 to 512 SIMS

2. SIM Server / IMEI Server Local SIM SERVER and Remote IP-SIM SERVER Local SIM Server New Concept of using SIMs with Mobile modules may be implemented on 1U or 3U 19” rack unit. Each unit may be a mix of cellular modules (4 on each card). The “user management” of SIM/Channel selection, will be done using dedicated s/w that will select the proper combinations of SIMs and Modules from the SIM Server. SIM & IMEI Remote Server Remote, IP-SIM Server – All SIMs are located remotely and used in different VoIP2ALL unit in different location. Configuration vary from 32 to 192 SIM for the 1U 19” rack system Configuration vary from 32 to 512 SIM for the 3U 19” rack system IMEI Server The SIM Server generates, periodically, a SIM image with an IMEI image to the destination channel/ports that is programmed by the dedicated s/w to work with, at that time.
