Model 2160 Series Getting Started Guide

Mode

There are two types of Line mode:
• STU-C: Central Office (CO) terminal
• STU-R: Customer Premise Equipment (CPE)

Link

Select the line type for your model. Line type means how many wires you want to use on the CopperLink con-
nection. For example, you can select 2-wire, 4-wire or 8-wire line type for the 8-wire model.

Annex Type

Enter the appropriate Annex type. Annex AF describes the transmission and performance requirements for
North America. Annex BG describes performance and transmission requirements for Europe.

TCPAM Type

TCPAM (Trellis Coded Pulse Amplitude Modulation) is the standard used for line coding. Select the TCPAM
type. Auto is the default option for TCPAM.

Maximum Main Rate

Select the line rate for your model. The main rate is the multiple of 64kbps, 128kbps, or 256kpbs- depending
on your model type. Use
Model Type
2-wire model
4-wire model
8-wire model

SNR Margin

SNR margin is an index of line connection quality. Generally, you won't need to change the SNR Margin. You
can view the actual SNR margin in status command menu.You will experience better line connection quality
for larger SNR margin values.
For example, if you set the SNR margin ias 5, the line connection will drop and reconnect when the SNR mar-
gin is lower than 5. On the other hand, the device will reduce the line rate and reconnect for better line con-
nection quality. You may select the SNR margin from the range -10 to 21.
