FORMAT Sets the frame format for the NI.
Choices: D4, ESF, AUTO
CODE Sets the line code for the NI.

YEL ALRM Enables and disables the transmitting of yellow alarms.
Choices: ENA (enable), DISA (disable)
XMIT ALRM Enables and disables the transmitting of performance report message (PRM) data on the
facility data link (FDL). The PRM data continues to be collected even if XMIT PRM is disabled
(possible only with ESF Format).

CLOCK SOURCE
Choices: NETWORK, DTE, INTERNAL
SET LBO Selects the line build-out (amount of attenuation, in dB) for the network interface.
Choices: 0, 7.5, 15, 22.5
a D4 is equivalent to Superframe Format (SF).
b For more information on clock sources and timing, see Clock Sources and Timing on page 40.

Clock Sources and Timing

The TSU LT operates from various clock sources, permitting it to perform properly in many different
applications. Use the
C
ONFIG
clocking options (network, DTE, or internal timing). See the descriptions for Network Timing on page 41,
DTE Timing on page 41, and Internal Timing on page 42.
The clocking option selected always designates the clock source for transmission.
Clocking necessary for receiving data is always recovered from incoming data.
