T1-Common Setting

(READ ONLY) Indicates the IP of the SIP server (SWE Edge SIP IP - 169.254.1.120) to which all SIP/IP requests will be sent if the PRI feature is enabled on the interface.

Specifies either T1 or E1.

Framing Mode Defines the number of frames that are grouped together for T1.

• T1—All T1 Framed modes use a 193-bit frame supporting one framing bit and 24 8-bit channels. There are 8000 frames per
  second with 1544000 bits per second data rate.
  • ESF—Extended Super Frame groups 24 193-bit frames together, making a 24-bit frame word. Six of the 24 bits are used for the
    framing pattern, and the other 18 bits are used for other services.
  • SF—Super Frame groups 12 193-bits frames together, making a 12 bit frame word. All 12 bits for the framing word are used for
    the framing pattern.
• E1—E1 supports three framing modes and an unframed mode. E1 Framed mode has a 2.048Mbit channel divided into 32 basic
  channels. Channel 0 is always reserved for framing and cannot be used for media. Channel 16 is the signaling channel and is used for
  different purposes. E1 frames are 256 bits (32 x 8bits). There are 8000 frames per second with 2048000 bits per second data rate.
  • Double Frame—Basic E1 mode. Two frames are form a 16-bit framing word (2 8bit samples of channel 0). PRI can be used,
    and channel 16 is typically used for the D-channel. No cyclic redundancy check (CRC) is performed in this mode.
  • Multi Frame CRC—Groups 16 256-bit frames together, creating a 128-bit framing word. Some of the framing bits are used to add
    a CRC-4 error check. PRI can be used, and channel 16 is typically used for the D-channel.
  • Unframed—No framing support and can be used for data.

The options are F24-ESF and F12-D3-D4.

Defines the bit encoding method used while transmitting data over the line. B8ZS (Bipolar 8 bit zero substitution) and AMI (Alternative Mark
Inversion) are currently supported.

The options are B8Z2 and AMI.
