SIP to ISDN PRI Signaling Converter is the powerful tool used to interface the telecommunications equipment and provide its interaction using various signaling systems.
Possible Titles ISDN PRI Signalings – Euro ISDN, E-DSS1, EDSS1, DSS1, QSIG, Q.931.
Using signaling converters helps to optimize capital expenditures when upgrading the network and extend the lifetime of the existing systems.
Key Features, Signalings, Protocols and Interfaces
The signaling and PCM30 protocol converter provides:
- converting signaling protocols of PCM30 digital links
- creating semipermanent connections
- dividing E1 port into channels
- converting the subscriber number when the connection is being established over the assigned masks
- visual monitoring of how system information flows in signal channels
- full-service switching of 16 PCM30 links
SIP to ISDN PRI Signaling Converter supports the following signaling protocols:
- SS7 (or Signaling System #7, CCS7 Common Channel Signaling System 7, C7, CCITT7, N7, Signalisierungssystem Nummer 7)
- ISDN PRI (or Euro-ISDN, E-DSS1, simply EDSS1, DSS1, QSIG, Q.931)
- R2 MFC
What is a PRI E1?
PRI or Primary Rate Interface – is a standard telecommunication interface of the ISDN digital network which is used to connect office PBX, central telephone exchanges or digital switches.
PRI E1 operates at a speed of 2.048 Mbps and consists of 32 channels (time intervals).
Management of PRI channels, combining telecommunication equipment into one PSTN network, occurs by using the following signaling protocols: DSS-1, QSIG, Q.931.
Design and Management
Technically, the product is designed as a dedicated industrial controller based on the state-of-the-art telecommunications processor. The Signaling Converter is designed to be installed in a server closet 19″ rack with 1U height of the housing.
Monitoring and control (changing configuration, monitoring operation etc.) are performed locally (RS-232 interface, COM1 port) or over Ethernet (TCP/IP).
Monitoring the operation of the device and reporting of accidents is carried out using the SNMP protocol.
Electrical power supply
The power is supplied from the DC source operating within from -36V to 72V range or from the AC source operating within from -90V to 265V range.
AC/DC redundancy power supply support. Power redundancy can be provided by installing two power sources that are operated concurrently with various configurations: AC 220V+AC 220V, AC 220V+ DC 48V/ DC 60V or DC 48V/60V+DC48V/60V.
