Gen Yellow: Enab

Next Enab Disab Prev

Generate Yellow Alarm Signals. Determines whether the DSU/CSU generates Yellow

Alarm signals on the network and DTE Drop/Insert (DSX-1) interfaces.

NOTE: This configuration option is not available for 1-port DSU/CSUs or if the DTE Drop/Insert (DSX-1) Interface is disabled. If the DTE Drop/Insert (DSX-1) interface is disabled, the DSU/CSU always generates the Yellow Alarm signal on the network interface.

Enab – Generates the Yellow Alarm signal for both the network and DTE Drop/Insert (DSX-1) interfaces.

Disab – Disables the Yellow Alarm signal. When this configuration option is disabled, Yellow Alarm conditions on the network interface cause an AIS signal to be transmitted on the DTE Drop/Insert (DSX-1) interface.

NOTE: When this configuration option is disabled, the DTE equipment connected to the DTE Drop/Insert (DSX-1) interface is responsible for generation of the Yellow Alarm signal on the network interface. In this case, the interface port marked DTE must only be connected to an FCC Part 68 Registered (for USA) and Canadian DOC Certified (for Canada) Digital Service Unit or System, such as PBX, with a DTE Drop/Insert (DSX-1) interface. Failure to do so is a violation of FCC Rules or DOC Regulations.

Clock Src: NET

Next NET DTE Prt1 Int Ext Prev

DSU/CSU Clock Source. Specifies the master clock source for the DSU/CSU. This selection synchronizes all internal timing and external interface clocks. The clock rate(s) for the external timing interfaces are independent of the input rate for the master clock. Failure of the clock specified by the Clock Source selection results in automatic fallback to internal clock.

NET – Configures the network interface as the master clock source.

DTE – Configures the DTE Drop/Insert (DSX-1) interface as the master clock source. This selection is not available for 1-port DSU/CSUs or if the DTE Drop/Insert (DSX-1) interface is disabled. If the DTE Drop/Insert (DSX-1) interface is disabled after making this selection, the master clock source is changed to NET.

Prt1 – Configures data port 1 as the master clock source. This is the only synchronous data port you can use for the master clock. If you enable EDL if for Port 1 and the DSU/CSU Clock Source is set to Prt1, the external device must provide clocking of

8 kbps less than the expected data port rate. For example, if you select 64 kbps, the external clock must supply a 56 kbps clock signal.

Int – Configures the internal clock as the master clock source.

Ext – Configures an external clock (provided through the Clock In connector) as the master clock source. This selection is only available on 2-port and 4-port DSU/CSUs.
