Chapter 2 NE- and CTM-Specific Details
2.2.5 Naming Conventions
For the ONS 155xx family, there is a new equipment holder called a port_holder. Because the TMF
determines whether or not a piece of equipment has to be in an EquipmentHolder, the port_holder is
created to hold the transceiver modules that contain the PTPs. A port_holder that is present in subslot 1,
slot 0 in an NE is named /rack=1/shelf=1/slot=1/sub_slot=2/port_holder=1. A port holder present in slot
1 in an NE is named /rack=1/shelf=1/slot=2/port_holder=1.
For the ONS 15600 NE and ASAP cards, a PIM present in slot 3 is named
/rack=1/shelf=1/slot=3/sub_slot=1. A PPM present in PIM 3 in slot 2 is named
/rack=1/shelf=1/slot=2/sub_slot=3/ppm_holder=1.
For AdditionalHolder, the naming convention is defined as /additionalHolder=1; there is no subholder
for AdditionalHolder. AdditionalHolders apply only to ONS 15454 SONET and SDH NEs when AIE or
AEP cards are installed.
For the MGX 8880/8850/8830, there is a new equipment holder called peripheral_holder. Because the
TMF determines whether or not a piece of equipment has to be in an EquipmentHolder, the
peripheral_holder is created to hold the peripherals.
A peripheral_holder present on a shelf is named rack=1/shelf=1/ /peripheral_holder=17236110, where
the number 17236110 is the unique peripheral ID.
A peripheral_holder in slot 1 is named /rack=1/shelf=1/slot=1/peripheral_holder=17236111, where the
number 17236111 is the unique peripheral ID.
2.2.5.8 Topological Link
CTM discovers topological links and assigns a name with the following default format:
MEName A:slot number/port number-ME Name B:slot number/port number
Integer values are used for slot and port number. You can use the CTM client to change the link name.
For the ONS 15530 and ONS 15540, the topological link name has the following format, where the port
number is optional:
ME NameA:InterfaceType/slot number/subslot number [/port number]-ME NameB:InterfaceType/slot
number/subslot number[/port number ]
For example:
• NE540A:Wdm0/0--NE540B:Wdm1/0
• NE540A:Wavepatch10/1/0--NE540A:Filter0/3/1
CTM reports two topological links for a Y-cable link. Both topological links have the same
nativeEMSName, but different values in the second tuple of the topological link name. The names
“<nativeEMSName>:::1” and “<nativeEMSName>:::2” identify the two legs of the Y-cable link.
2.2.5.9 Protection Group
The protection group name reported by the NE is used as the PGP native name for 1_FOR_1, 1_FOR_N,
and 1_PLUS_1 protection groups. The ring ID is used as the PGP native name for 2_FIBER_BLSR and
4_FIBER_BLSR protection groups. “<Ring Id>-EAST” and “<Ring Id>-WEST” are used as the native
names for the two component groups of 4_FIBER_BLSR PGP.
