Parameters
115391-A Rev. A A-49
Parameter: Line Type
Path: MCT1 Connector > Edit Logical Lines > Port Details > MCT1 Port
Parameters
Default: ESF
Options: Unframed T1
| ESF | SF/D4
Function: Specifies the framing format.
ESF transmits superframes consisting of 24 individual SF/D4 frames and
provides enhanced signaling and synchronization.
SF/D4 transmits superframes consisting of 12 individual frames.
Instructions: Select the appropriate frame format for your T1 equipment. Use Unframed T1
only with BERT mode to match the line type.
MIB Object ID: 1.3.6.1.4.1.18.3.4.9.4.1.6
Parameter: Line Coding
Path: MCT1 Connector > Edit Logical Lines > Port Details > MCT1 Port
Parameters
Default: B8ZS
Options: AMI
| B8ZS
Function: Specifies a line coding method. AMI line coding is bipolar: a binary 0 is
transmitted as zero volts and a binary 1 is transmitted as either a positive or
negative pulse, opposite in polarity to the previous pulse. (When configured for
AMI line coding, the MCT1 link module remains synchronized upon receiving
up to 45 consecutive 0s.)
B8ZS (bipolar with 8-zero substitution) line coding replaces a block of eight
consecutive binary 0s with an 8-bit B8ZS code containing bipolar violations in
the fourth and seventh bit positions of the substituted code. In the receive
direction, the B8ZS code is detected and replaced with eight consecutive
binary 0s.
Instructions: Select the line coding method.
