Notes:
1. Stations whose line loop resistances range between 400 and 1600 ohms must terminate on an
OPS line card.
2. External wire resistance measurements are based on the assumption that a 200 ohm set was
used.
3. The German variant also provides impedance matching, fixed and variable gains, as well as Tip
and Ring protection, with selectable fuse or EMI choke option.
4. The message waiting circuit for the ONS CLASS/CLIP line card has a voltage below 120v on the
ring lead.
Operation
Incoming analog calls are converted to digital (PCM) signals by one of 16 line circuit modules
on the ONS line card. Calls are switched by the Main Controller and the two parties are
