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 stream 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
R2 CAS to SS7 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)
- V5.2
- R2 MFC
- R1.5
- SIP (option)
Implementation of the SS7 and the number of links supported
Signaling System No. 7 (or SS7) is a globally accepted protocol for out-of-band signaling systems and is regulated by the International Telecommunication Union (ITU-T).
R2 CAS to SS7 Signaling Converter from Terratel covers the full functionality of the MTP2, MTP3 and ISUP subsystems in accordance with ITU standards and guidelines.
R2 CAS to SS7 Signaling Converter allows you to organize from 1 to 16 links on 16 E1 ports.
Accordingly, for a device with physically installed 8E1 ports, support from 1 to 8 SS7 links is possible. Those, оn 1E1 port – 1 link SS7.
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.
