ATLAS 800 Series System Manual NxT1 HSSI Option Module
HSSI/V.35 Menus
HSSI/V.35 Menus
Read Security: 5
Provides status, configuration, and testing parameters for the 50-pin SCSI-II HSSI interface.
Status Read Security: 5
Displays the current loopback status of the HSSI interface.
Submenus Description
Port
Indicates the port number.
Ifce Type
Interface type depends on the module’s current status and/or the type of cable
connected to its DTE interface.
Loopback
Displays the current loopback status of the HSSI interface. See Figure 13 on
page 175.:
Local DTE A local DTE loopback occurs at the DTE port of the DCE, and
is used to test the link between the DTE and DCE (NxT1HSSI
module).
Local Line A local line loopback occurs in the IMUX engine and is used to
test functionality between the DTE and the IMUX engine.
Remote Line A remote line loopback occurs at the T1 interface and is used to
test functionality between the DTE and the T1 interfaces.
LA and LB
Displays the status of the loopback circuit A and B signals. LA and LB are
asserted by the DTE to enable a loopback on the DCE and its associated data
communications channel. The options include the following:
LA
LB Loopback
Off Off No Loopback Active
On On Local DTE Loopback is Active
On Off Local Line Loopback is Active
Off On Remote Line Loopback is Active
Displays the status of the data Terminal equipment
AVAILABLE signal. TA will be
asserted by the DTE (independently of CA) when the DTE is prepared to both
send and receive data to and from the DCE. Valid data transmission should not
commence until CA has also been asserted by the DCE. If the data
communications channel requires a keep alive data pattern when the DTE is
disconnected, then the DCE shall supply this pattern while TA is de-asserted.
When using the NxT1 HSSI Module (1200346L2 only) in V.35 mode, TA
displays the status of the Request to Send (RTS) signal. When RTS is active in a
V.35 configuration, Clear to Send (CTS) is also active.
