T1 Frame Type, T1 Loop Back | Cabletron Systems 2000 specification

HSIM-W87 Conﬁguration

Valid Intervals

Displays the number of previous intervals for which valid data was collected. The value will be 96 unless the interface was brought online within the last 24 hours, in which case the value will be the number of complete 15-minute intervals since the interface has been online.

T1 Frame Type

Displays the type of service you are using over your T1 line. This value should be set according to your WAN service providerÕs instructions: ESF (Extended Super Frame DS1) or D4 (AT&T D4 format DS1).

T1 Loop Back

Displays the loopback conÞguration of the T1 interface. Values are:

No Loop	Not in a loopback state. A device that is not capable of
	performing a loopback on the interface will always have this
	value.
Payload	The received signal at this interface is looped through the device.
	Typically the received signal is looped back for retransmission
	after it has passed through the devicesÕs framing function.
Line Loop	The received signal at this interface does not go through the
	device, but is looped back out.

Line Status

This Þeld indicates the line status of the interface. It contains loopback, failure, received alarms and transmitted alarm information.

T1 Line BuildOut

Displays the value of the Line Buildout setting. This setting controls the amount of attenuation of the T1 signal. The possible settings are 0 db, -7.5 db, and -15 db. This Þeld is currently not supported and will appear grayed out.

Transmit Clock Source

Displays the T1 Transmit Clock Source: Loop-Timing, which indicates that the recovered receive clock is used as the transmit clock, and Local-Timing, which indicates that an internal clock source is used.
