7 Configuration Command Reference
Syntax
MTP HSL/LSL Links
MTP_LINK <link_id> <linkset_id> <link_ref> <slc> <board_id> <blink> <stream> <timeslot> <flags>
[<data_rate>]
Example
MTP_LINK 0 0 0 0 0 0 0 16 0x0006 TDM
ATM Links
MTP_LINK <link_id> <linkset_id> <link_ref> <slc> <board_id> <blink> <atm_stream> <vpi-vci> <flags> ATM
Example
MTP_LINK 0 0 0 0 3 0 0 8-100 0x0006 ATM
Common Parameters
The MTP_LINK command includes the following parameters:
• <link_id>
The unique logical identity of the link. It must be in the range 0 to one less than the total number of
signaling links supported.
• <linkset_id>
The logical identity of the linkset to which the link belongs. The linkset must already have been
configured using the MTP_LINKSET command.
• <link_ref>
The logical identity within the linkset of the signaling link. It should be in the range 0 to one less than the
number of links in the linkset.
• <slc>
The signaling link code for the signaling link. This must be unique within the linkset and is typically the
same as <link_ref>. The valid range is 0 to 15.
• <flags>
A 32-bit value containing additional run-time options. The bit significance is as follows:
Note: If the <data_rate> is set to "ATM", only bits 0 to 2 are significant.
— Bit 0 is set to 1 to force the use of the emergency proving period during link alignment or 0 to use
the appropriate proving period according to the MTP3 recommendations.
— Bit 1 is set to 1 to cause a signaling link test (in accordance with ITU-T Q.707 / ANSI T1.111.7) to be
carried out before a link is put into service, or 0 if a test is not required.
— Bit 2 is set to 1 to cause a signaling link test (in accordance with ITU-T Q.707 / ANSI T1.111.7) to be
carried out every 30 seconds. This bit is ignored unless bit 1 is set to 1.
— Bit 8 is used to select the MTP2 error correction mode. It is set to 1 to select PCR (Preventive Cyclic
Retransmission) operation or 0 for the Basic Method of Error Correction.
— Bits 10 and 11 together select the appropriate operating bit rate for the link. The table below
specifies the appropriate values for 48, 56, or 64 kbits/s.
Bit 10 Bit 11 Data Rate
0 0 64 kbits/s
0 1 48 kbits/s
1 0 56 kbits/s
11Reserved
Note: For framed HSL operation, these bits select the bit rate for
each slot of the HSL link.
