Using signaling converters helps to optimize capital expenditures when upgrading the network and extend the lifetime of the existing systems.

Key Features

The signaling and PCM protocol converter provides:

  • converting signaling protocols of PCM30 digital links
  • creating semi-permanent connections
  • dividing E1 links 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 PCM links

Signalings, Protocols and Interfaces

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, EDSS1, DSS1, QSIG protocols, recommendation Q.931)
  • V5.2
  • R2 MFC
  • R1.5
  • SIP (option)

Applications Signaling Converter SS7, ISDN PRI, V5.2, CAS

The equipment will realize converting of signaling in different configurations:

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.
