Application
Balanced Impedance
(BIMP):
Note:
5. Gain treatment, such as a Voice Frequency Repeater (VFR) is required to limit the
actual OPS loop loss to 4.5 dB, maximum. VFR treatment of metallic loops having
untreated loss greater than 15 dB (equivalent to a maximum signaling range of 2300
ohms on 26 AWG wire) is not recommended.
Note:
6. Jumper strap settings JX.0 and JX.1 apply to all eight units; "X" indicates the unit
number, 0 – 7. "Off" indicates that a jumper strap is not installed across both pins on a
jumper block. Store unused straps on the OPS analog line card by installing them on a
single jumper. pin.
