Плата расширения Avaya/Lucent Definity TN464F Universal DS1 ISDN/PRI Interface

Описание

• Board-level, administrable A-Law or µ-Law companding
  
• CRC-4 generation and checking (E1 only)
  
• Stratum 3 clock capability
  
• ISDN-PRI T1 or E1 connectivityThe TN778 packet-control circuit pack and the TN765 processor interface (R7 or later si) or TN1655 packet interface (R7 or later r) handle D-channel signaling for the TN464.
  
• Line-out (LO) and line-in (LI) signal leads (unpolarized, balanced pairs).
  
• Support for CO, TIE, DID, and off-premises station (OPS) port types that use robbed-bit signaling protocol, proprietary bit-oriented signaling (BOS) 24th channel signaling protocol, or DMI-BOS 24th channel signaling protocol
  
• Support for Russian incoming ANI (R7 or later)

TN464C and later circuit packs can be used as universal, digital, signal level-1 boards in wideband ISDN-PRI applications.
