E1 GSM Gateway with 90 SIMs
for VoIP termination |
| |
The latest E1 GSM Gateway with 90 SIMs (3
SIMs per each GSM channel - 90 SIMs per E1). Each GSM channel individual programmable to work with any of the 3 SIMs
assigned to that GSM channel according to
the "user" programmed time-table ("user" programmed time-of-day schedule).
This enables the user to program a least-cost operation so that traffic, at
any time-of-day, is only directed to the preferred SIM (out of the
3 SIM cards per GSM channel) - which shall activate only according to the "user"
programmed time-table ("user programmed time-of-day schedule). The latest compact E1 GSM Gateway solution
integrates the E1 interface to the GSM network to provide the user with 30, GSM links (90 SIMs) for mobile communications with an integrated E1 interface. |
