One signaling element per second. This is a measure of the signaling rate on the telephone line. It should not be confused with Bits Per Second (bps) which can differ from the Baud rate.

Bit mapping is a technique that allows a single S-Register to hold up to 8 binary variables e.g.:
Reg Type Val Default Function
S14 Bit Mapped 170 Register S14 is a bit-mapped register and provides the following functions:
Bit 0 Reserved
Bit 1 Echo commands to DTE
Bit 2 Responses
Bit 3 Word or number responses
Bit 4 Reserved
Bit 5 Dialing method

The Iridium Gateway will send a ‘Ring Alert’ to the Transceiver when a Mobile Terminated SBD (MT-SBD) message has been queued at the Iridium SBD Gateway. Your mobile application can then decide whether to retrieve the MT-SBD data message at that time or later.<\/p>\n","protected":false},"excerpt":{"rendered":"
