Qslac

Syntax

Qslac [m[..n]] = filename.slc

Description

Specifies the country-specific file for line interfaces for AG 2000 boards. m, n optionally specifies a port or a range of ports.

There are two QSLACs (Quad Subscriber Line Audio - Processing Circuits) on an AG 2000 board. The first QSLAC services ports 0 - 3. The second QSLAC services ports 4 - 7. Each port can be configured separately; the configuration is contained in a QSLAC file. Each QSLAC file is customized for a specific line interface signaling module and for a certain country's two wire return loss requirements.

All QSLAC files have an extension of .slc. All QSLAC files adhere to the following naming convention:

[pp][cty][ss][i].slc
Where...

 Represents the...

 For example...

pp

 Two-character NMS product field.

 a2 = AG 2000 board

q3 = QX 2000/80-4L

q4 = QX 2000/100-4L

w8 = WTI-8 board

cty

 Three-character ISO country code or region code.

ss

 Two-character signaling type.

 ls = loopstart

dd = DID

sl = subscriber loop

2w = Two wires E&M

4w = Four wires E&M

i

 One character line impedance field.

 6 = 600 ohm

9 = 900 ohm

n = lines longer than 2000 feet

c = complex (used in some international markets)

The Natural Access installation program configures the system for the QSLAC file that is intended for your country. Do not change the configuration unless you are confident that a change is required and is allowed by the regulatory agencies.

For more information about QSLAC files, refer to the AG CAS Installation and Developer's Manual.

If the default file is not used, an entry will be made in the error log file at boot time. If echo cancellation is enabled, there4 is no benefit in changing from the default QSLAC file.

Example

Qslac 2..4 = a2usals9.slc
