● Framing at 12 kbps
● Maintenance at 4 kbps
The TN2198 supports a maximum of 24 telephones or data modules.
The TN2198 is not offered as a BRI Tie Trunk.
TN2199 central office trunk (3-wire, 4 ports)
TN2199 central office trunk (3-wire, 4 ports)
The TN2199 central office (CO) trunk circuit pack is designed for use in Russia.
The TN2199 is a 4-port, 3-wire, loop-start trunk circuit pack that can be used as a:
● DID trunk
● Two-way, one-way incoming, or one-way outgoing CO trunk
The TN2199 combines the functionality of a DID trunk and a one-way outgoing CO trunk (DIOD
trunk). To accomplish MF shuttle signaling, the TN2199 circuit pack must be combined with a
TN744D Call Classifier circuit pack.
The TN2199 circuit pack supports incoming automatic number identification (ANI).
TN2202 ring generator
The TN2202 ring generator circuit pack is designed for use in France.
The TN2202 ring generator circuit pack supplies 50-Hz ringing power. The TN2202 supplies
balanced ringing to telephones that connect to the TN2183/TN2215 multicountry analog line
circuit pack. A modified backplane allows this balanced ringing. The telephones must be
administered for France analog transmission.
The TN2202 plugs into the power unit slot and is required for each carrier that contains analog
lines requiring 50-Hz ringing. A 1-lead modification is required in a carrier backplane that uses
the TN2202. This modification is required for all products that are made for France. The TN2202
can:
● produce two symmetric voltages (usually 28 V RMS) with respect to ground,
● take –48 VDC, –5 VDC, and ground from the backplane, and
● generate 2 × 28 V RMS with added –48 VDC.
For CMC1 systems, this circuit pack is not needed.
