Chapter 5. Configuration Menu

NETWORK (NI)

This menu item accesses the configuration of parameters associated with the network interface in the base unit. There are eight sub- menu items that include setting the format, the line build out (LBO), and the timing mode.

Network (NI) Menu Items

The menu items are:

Menu Item	Description
Interface	Selects either the 120Ω DB15 interface or the 75Ω BNC
(INTFACE)	interface.
	Choices: 120Ω, 75Ω. BAL and 75Ω UNBAL
	In 75Ω UNBAL mode, both the Tx and Rx are shield
	grounded.
Framing	NFAS Word. If enabled, the network interface receiver
	requires the NFAS word (TS0 in odd frames) and the FAS
	word (TS0 in even frames) for frame sync. When disabled,
	only the FAS word is needed for frame sync.
	Choices: Enable, Disable
CAS/TS16	Enables/Disables Channel Associated signalling (time slot
	16 multiframing). When this menu option is enabled, the
	following occurs:
	1. The TS16 multiframe alignment signal is inserted in the
	outgoing data stream.
	2. Signaling Bits are transmitted in TS 16 for all TS0s that are
	mapped to a signalling-capable port (Base Drop port, for
	example). In TS0s that are mapped to “Idle” or data ports,
	“1s” are transmitted in the signalling bit positions.
	3. The TS16 multiframe alignment signal must be received
	for frame sync.
