Provisions the BITS In facility type (DS1 or 64 Khz).
|
|
Provisions the BITS In state to In-Service (IS) or Out-of-Service (OOS).
If Timing Mode is set to External or Mixed, set the BITS In State for BITS-1 and/or BITS-2 to IS, depending on whether one or both BITS input pin pairs on the backplane are connected to the external timing source. If Timing Mode is set to Line, set the BITS In State to OOS.
|
|
Sets the coding used by your BITS In reference, either B8ZS or AMI.
|
|
Sets the framing used by your BITS In reference, either Extended Super Frame (ESF), or Super Frame (SF) (D4).
|
|
If checked, enables the SSM for BITS In. (SSM is not available if Framing is set to Super Frame.)
|
|
(ONS 15310-CL and ONS 15454 only) If the Sync Messaging check box is not checked, you can choose the SSM Generation 2 type from the drop-down list.
|
|
|
Provisions the BITS Out facility type (DS1 or 64 Khz).
|
|
Provisions the BITS Out state to IS or OOS.
If equipment is connected to the node’s BITS output pins on the backplane and you want to time the equipment from a node reference, set the BITS Out State for BITS-1 and/or BITS-2 to IS, depending on which BITS Out pins are used for the external equipment. If equipment is not attached to the BITS output pins, set the BITS Out State to OOS.
|
|
Sets the coding used by your BITS Out reference, either B8ZS or AMI.
|
|
Sets the framing used by your BITS Out reference, either ESF or SF (D4).
|
|
If SSM is disabled or Super Frame is used, sets the quality level where a node sends an alarm indication signal (AIS) from the BITS-1 Out and BITS-2 Out backplane pins. An AIS is raised when the optical source for the BITS reference falls to or below the SSM quality level defined in this field.
|
|
When timing external equipment connected to the BITS Out pins, sets the distance between the device and the ONS node. Options are 0-133 ft. (default), 134-266 ft., 267-399 ft., 400-533 ft., and 534-655 ft.
