10 QuickSET Configuration Guide

This section explains how to conﬁgure the Wide Area T1 interface using QuickSET.

The line conﬁguration information shown must be supplied by your service provider. Factory

default settings are in bold.

The following deﬁnitions explain the ﬁelds in the T1 WAN conﬁguration window.

T1 Frame Type — Displays the T1 frame type. The selections are ESF (Extended Superframe)

and D4 (AT&T D4). The default setting for this ﬁeld is ESF.

T1 Line BuildOut — Displays the signal level for the physical T1 line. Set this to 0 dB unless the

service provider recommends another setting. The default setting for this ﬁeld is 0 dB. The

following options are available for this setting: 0 dB, -7.5 dB, and -15 dB.

T1 Line Coding — Displays the line coding for the physical T1 line. The selections for this ﬁeld

are B8ZS and AMI. The default setting for this ﬁeld is B8ZS.

T1 Loop-Back — Network Loopback is a testing procedure that segments the line and allows you

to isolate faults. The selections for this ﬁeld are No Loop and Line Loop. In Line Loop all 24

channels are looped back to the T1 line. The CyberSWITCH or HSIM must be in Loop-Timing

mode to use this option. The default setting is No Loop.

T1 Transmit Clock Source — Displays the T1 Transmit Clock Source. The choices for this ﬁeld

are Loop-Timing (Extracted Line Data) and Local-Timing (Internal Clock). The default setting for

this ﬁeld is Loop-Timing.

Protocol — Displays the active protocol for the Wide Area interface. The Protocol panel lets you

select either Frame Relay or Point-to-Point.

Link Management Protocol — If you selected Frame Relay protocol, this ﬁeld displays

Q.933 Annex A, or T1.617 Annex D. The default is T1.617 Annex D. This ﬁeld is grayed out and

not used for PPP.

When you have completed Wide Area T1 conﬁguration, click on N

ext>>, and go to the Wide

Area Frame Relay Time Slot Configuration Window or Wide Area PPP Time Slot

Configuration Window section, depending on which protocol you are using.
