Table 3-8 Aps Line Architecture Modes - Cisco MGX 8850 (PXM1E/PXM45) Configuration Manual

Chapter 3 Provisioning PXM1E Communication Links
• The working line must be assigned to a lower numbered port than the protection line. For example,
the working line could be on port 3 and the protection line on port 4. If the protection line is on port
2, do not assign the working line to port 3.
• The switches at both ends of the APS lines must be configured for APS, and the role of each line
(working or protection) must be the same at both ends of the line.
To establish redundancy between two lines on the same card, use the following procedure:
Establish a configuration session using a user name with GROUP1_GP privileges or higher.
Step 1
If you have not done so already, bring up the working line as described in
Step 2
appears earlier in this chapter.
Step 3 Enter the addapsln command as follows:
mgx8830b.2.PXM.a > addapsln <workingIndex> <protectIndex> <archmode>
Replace <workingIndex> with the location of the working line using the format slot.bay.line. For
example, to specify the line on card 2, bay 2, line 1, enter 1.2.1.
Note When specifying the slot number for the working line, always refer to the logical slot number, which is
1 for MGX 8830 switches and 7 for MGX 8850 switches. For example, in the previous paragraph, the
working line is connected to slot 2, bay 2, line 1, but you must enter 1.2.1 to refer to this line.
Replace <protectIndex> with the location of the protection line, using the format slot.bay.line. For
example, to specify the line on card 2, bay 2, line 2, enter 2.2.2.
Note When specifying the slot number for the protection line, always refer to the physical slot number. For
example, in the previous paragraph, the working line is connected to slot 2, bay 2, line 2, so you must
enter 2.2.2 to refer to this line.
Replace <archmode> with the option number that selects the APS architecture mode.

APS Line Architecture Modes
Description
Selects 1+1 Bellcore GR-253 APS protocol signaling (transmission on both working and
protection lines).
Selects 1:1 Bellcore GR-253 APS protocol signaling (transmission on either the working
line or the protection line) for intracard APS.
Selects 1+1 ITU-T G.783 AnnexB APS protocol signaling (transmission on both working
and protection lines).
Selects 1+1 Y-cable signaling without K1 and K2. This option is not supported for
intercard or intracard APS in this release.
Selects 1+1 straight cable signaling without K1 and K2.
