: | Number of Links
: | Link n: ID
: | Link n: Status This field is a bit mask. The meaning of each bit is as follows: Bit Status 0 Available 1 Failed 2 Inhibit Locally 3 Inhibit Remotely 4 Remote Blocked 5-7 Reserved
: | Signaling Link Code (n) The signaling link code (SLC) must be the same on both ends of the link (0x00–0x0F).
: | Data Rate (n) This field specifies a bit mask that determines the data rate. If any one bit is set, the data rate will be 56 Kbps. If any two bits are set, the data rate will be 48 Kbps. The most common settings for this field are: 0x00 64 Kbps 0x01 56 Kbps for non-V.35 applications (mask off least significant bit) 0x80 V.35, 56 Kbps (mask off most significant bit) 0x81 48 Kbps for non-V.35 applications (mask off least significant and most significant bits) 0xC0 V.35, 48 Kbps (mask off 2 most significant bits)
: | Electrical Interface (n) 0x00 No timing (Not a V.35 link) 0x01 V.35, DTE (Data Terminal Equipment) 0x02 V.35, DCE (Data Communications Equipment) In addition, Bit 8 specifies data inversion of the V.35 data stream. The data inversion is performed on the SS7 MP I/O card. 0x81 Invert Transmit and Receive Data For example, if the Electrical Interface Byte is 0x81, data inversion is performed on both Transmit and Receive Data, and the interface is V.35 DTE.
: | AIB (Individual AEs) Span/Channel that Link (n) is on. 0x0D Channel
: | Checksum

Data Terminal Equipment. According to the RS-232-C standard, DTE devices are typically personal computers or data terminals. See DCE.
Data Communications Equipment. According to the RS-232-C standard, DCE devices are typically modems or printers. See DTE.
Range of channels provided by T1 or E1 transmission service. A physical span is a group of channels taking up a single physical wire. A logical span is a group of channels taking up less than a single logical wire, or carried over more than one physical wire.
