NT1R20 Off Premise Station (OPS) analog line card
553-3011-100
Standard 14.00
January 2002
Port-to-port loss configuration
The loss plan for the OPS analog line card determines port-to-port loss for
connections between an OPS analog line card unit (port) and other Meridian 1
PE or IPE ports.
The transmission properties of each line unit are characterized by the OPS or
ONS class-of-service assigned in the Single-line Telephone Administration
program (LD10).

a.
Configured in the Single line Telephone Administration program (LD 10).
b.
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.
c.
Loss of untreated (no gain devices) metallic line facility. Upper loss limits correspond to loop resistance
ranges for 26 AWG wire.
d.
Default software impedance settings are:
ONS CLS
OPS CLS
TIMP:
600 ohm

BIMP:

e.
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 15dB
(equivalent to a maximum signaling range of 2300 ohm on 26 AWG wire) is not recommended.
