TN464C/D/E/F/G
All TN464 circuit packs provide
- 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 connectivity
- 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)
The TN778 packet-control circuit pack and the TN765 processor interface (R7si ) or TN1655 packet interface (R7r) handle D-channel signaling for the TN464.
TN464C and later circuit packs can be used as universal, digital, signal level-1 boards in wideband ISDN-PRI applications.
TN464E and later circuit packs provide test-jack access to the DS1 or E1 line and support the 120A Integrated Channel Service Unit (CSU) module.
TN464F/G (US and Canada Offer A Only) circuit packs use the enhanced maintenance capabilities of the ICSU. These circuit packs can communicate with CONVERSANT ®. See TN2185B.
