DEFINITY Hardware
TN2207
The TN2207 circuit packs support digital signal level 1 (DS1) rate (24 channel) and E1 rate (32 channel) digital facility connectivity. All TN2207 suffixes support CO, Tie, DID, and off premises station (OPS) port types using the robbed-bit signaling protocol, the proprietary Bit-Oriented Signaling (BOS) 24th channel signaling protocol, and the DMI-BOS 24th channel signaling protocol. The circuit packs also support ISDN-PRI connectivity T1 or E1.
In DS1 (24 channel) mode, a DS1 interface is provided to the DS1 facility. The TN2207 circuit packs provide board-level administrable A-Law and µ-Law companding, CRC-4 generation and checking (E1 only), and Stratum 3 clock capability.
The TN2207 provides test jack access to the DS1 or E1 line and support the 120A integrated channel service unit (CSU).
All suffixes have line out (LO) and line in (LI) signal leads. The Line Out and Line In leads are unpolarized balanced pairs.
The TN2207 has additional hardware to support direct cabling to a TN787 MMI circuit pack.
