Introduction
Use the following parameters table to configure encoding and framing settings for all T1 portslines.
T1-Common Setting
| Parameter | Description |
|---|
| SIP-SERVER-IP | (READ ONLY) Indicates the IP of the SIP server (SWE Edge SIP IP - This field is read-only, with a value of 169.254.1.120. The value represents the SWe Edge internal IP address (Ethernet 2 IP address) to which all SIP/IP requests will be sent if the PRI feature is enabled on the interfaceused for SIP signaling to and from the SIP Gateway (PRI-Gateway-Virtual-IP) to support PRI calls. |
| Framing ModeSpecifies either T1 or E1. | Framing Mode Defines mode defines the number of frames that are grouped together for T1. T1—All All T1 Framed framed modes use a 193-bit frame supporting one 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 Options are F24-ESF and F12-D3-D4. |
| Line-Encoding | Defines the bit encoding method used while transmitting data over the line. Options are: the line. B8ZS (Bipolar 8 bit zero substitution) and AMI (Alternative Mark
Inversion) are currently supported.The options are B8Z2 and AMI. |
