For more information about supported DS3 PM parameters for the DS3VTx12
mapper, see Table 2-23 on page 2-108.
For more information about supported DS1 PM parameters for the DS3VTx12
mapper, see Table 2-24 on page 2-109.
Equipping rules
The DS3VTx12 mapper can be installed in slots 3 through 10. DS3VTx12
mappers are installed in pairs. The first DS3VTx12 mapper of the pair is
installed in an odd slot. The second DS3VTx12 mapper of the pair is installed
in the adjacent even slot. The second DS3VTx12 mapper functions as the
protection DS3VTx12 mapper for the working mapper in the odd slot.
Note: The maximum number of working DS3VTx12 mappers that can be
inserted in an OPTera Metro 3500 shelf is four.DS3/VTx12 mapper is
supported on OPTera Metro 3500 shelves equipped with VTX- series
circuit packs in slots 13 and 14.
DS3/VT protection switching
DS3VTx12 protection switching is 1+1 non-revertive. If a working
DS3VTx12 mapper becomes defective, the traffic is switched to the protection
DS3VTx12 mapper. Switching can also take place under user control.
Alarm LED definitions
The following table provides a list of the DS3VTx12 mapper LEDs. See Figure
3-28 on page 3-47 for the DS3VTx12 mapper faceplate layout showing the
location of the LEDs.
2x100BT-P2P circuit pack
(NTN433AA)
This circuit pack gives users native Ethernet, using standard STS-1 or STS-3c
connections without the need for SNMP or BCC management.
Note 1: The 2x100BT-P2P circuit pack only supports far-end link
conditioning at 100Mb/s (100BASE-TX).
Note 2: The 2x100BT-P2P circuit pack is only supported in the
operational temperature range of 0°C to 50°C (32°F to 122°F).
LED Color Description
Status Red Circuit pack failure
Active Green DS3x12 equipment is active and at least one DS3
line facility is in service with at least one
cross-connect
