Q.SIG
This feature allows the SOPHO 2000 IPS to provide basic connection service when
interfacing to a QSIG network. A 30 B-channel 2Mps (E1) digital interface with a Q.SIG
D-channel handler (SPN30PRTA-QSIG) card is required for each physical interface.
QSIG Overlap Sending/Receiving (R9)
R9 enhancement provides an option to use overlap sending/receiving for QSIG, based on
ETS 300 172. Max 32 digits of the called number can be sent/received with SETUP +
INFO message(s); in case of tandem connection, max. 24 digits of the called number.
Tandem connection is supported for a call from/to ISDN, CCIS, QSIG, E1/T1 or analog
E&M trunk.
Note: In the overlap sending, T304 timer is fixed as 15s (though ETSI defines 20s or
more).
Required Hardware: SPN-30PRTA-QSIG(AP) or SPN-24PRTA-QSIG(AP).
Remote Hold
This feature allows a Multiline Terminal user to hold it on the line button of transferred
terminal, by pressing the Hold key.
Remote MP Software Download (R10)
This feature provides a remote MP software download function via an IP network when
the system is on-line mode. By the command from the MATWorX, the MP software
stored in the external FTP server is downloaded to the MP. The downloaded software
stored in the MP is changed over to the existing working MP software immediately after
the download is completed or based on the schedule programmed by the MATWorX. If
the changeover fails, fallback to the old software can be executed.
This feature provides an easy way for software updates from a remote maintenance center
to systems dispersed geographically.
Required Software and Hardware:
- SPN-CP24C MP (PBC)
- SPN-CP31C MP (PBC); Note: When the SPN-CP31C is used for remote site MP in
the Remote PIM network, the remote software download feature is not supported.
- MATWorX IPS for R10
Remote PIM over IP
When IPS DMR and 2000 IPS PIM are installed at remote site, and connected to a 2000
IPS or IPS DM at main site over IP network, the Main Site system controls and maintains
the IP Remote PIM operation as one single system. If a communication failure occurs
