Syntax Description (T3/E3)
All parameters are keyword driven. Therefore, the order that you enter them does not matter.
-ds3 Identifies the bay (1 or 2) and the number of the line. The format for LineNum is
bay.line. The line number is from 1 to the highe st numb ered l ine o n the b ack card . Fo r
the range of line numbers on specific AXSM models, see Table 3- 1.
-lt Specifies the type of T3 line. The possible value for a T3 LineType is 1 or 2:
•1 = ds3cbitadm
•2 = ds3cbitplcp
-len The length of the line in meters. The range for LineLength is 1–64000.
-oof A number that specifies the threshold fo r tr ig ge ring an Out Of Frame condition. Th e
possible value for LineOOFCriteria is 1 or 2 and has th e fo ll owi ng s i gn ifican ce:
•1 = 3 out of 8
An Out Of Frame condition is decl ar ed if at lea st 3 of 8 framing bits are in error.
•2 = 3 out of 16
An Out Of Frame condition is declared if at least 3 of 16 fr aming bits are in error.
-cb A number that determines whet her the node checks the C-bit status in response to AIS
status. The value for LineAIScBitsCheck can be 1 or 2 and has the following
significance:
•1 = check the C-bit
•2 = ignore the C-bit
-rfeac Value to set FEAC (far-end alarm and control) code validation criteria. The value for
LineRcvFEACValidation can be 1 or 2 and has the fol low in g s ig nificance:
•1 = 4 out of 5. A valid FEAC code is declared if 4 of 5 codes match.
•2 = 8 out of 10
A valid FEAC code is declared when 8 of 10 codes match.
-clk A number that determines whether th e transmit clock comes from the ba ck pl an e
(“local timing”) or the rec eive clock on the line ( “lo ope d tim ing”). The value for
clockSource can be 1 or 2 and has the following significance:
1 = loop timing: receive clock is re-directed on the back card to be the transmit clock.
2 = local timing: (default) clo ck f r om th e backplane is the transmit cloc k.
