After the restoration of an SDSL link, the NE (AM) must refresh the entire V-LAN
table with the V-LAN Table command. Refreshing the V-LAN table with the V-LAN
Table command is not allowed to result in the interruption of individual or of all
V-LANs.
NTU LPT Support
The 1643 AM / 1643 AMS supports Link Pass Through (LPT) functionality via EOC
commands.
Users can enable or disable LPT using the following parameters.
• CA-CSF: GFP Client Signal Fail Signalling
• CA-SSF: Disabling LAN interfaces during WAN connection failure
NTU Ethernet QoS support
The 1643 AM / 1643 AMS provides enhanced PM support for third party NTUs. It
supports a two port Ethernet SHDSL modem (NTU) which is connected via 1 to 4
parallel TU-12s over SHDSL mapped links. The Enhanced NTU ETH LAN port PM
counters are available via the QD2-Lite extension. The Ethernet traffic bandwidth is
optimized by GFP-F encapsulation and VC-12-Xv virtual concatenation using LCAS.
The 1643 AM / 1643 AMS supports the following NTU Ethernet QoS functions.
• PriorityMode
• IngressRateControl
• CIRAverageBitRate
• CIRMaxBurstSize
• PortPriority
NTU software download
The 1643 AM / 1643 AMS provides enhanced PM support for third party NTUs. It
supports a two port Ethernet SHDSL modem (NTU) which is connected via 1 to 4
parallel TU-12s over SHDSL mapped links. The Enhanced NTU ETH LAN port PM
counters are available via the QD2-Lite extension. The Ethernet traffic bandwidth is
optimized by GFP-F encapsulation and VC-12-Xv virtual concatenation using LCAS.
The 1643 AM / 1643 AMS can use up to four SHDSL links in parallel via z-bits to
download NTU software.
NTU web interface
The OMS of the 1643 AM / 1643 AMS can be used to set user passwords for the NTU
web interface.
NTU general configuration support
The 1643 AM / 1643 AMS provides enhanced PM support for third party NTUs. It
supports a two port Ethernet SHDSL modem (NTU) which is connected via 1 to 4
parallel TU-12s over SHDSL mapped links. The Enhanced NTU ETH LAN port PM
counters are available via the QD2-Lite extension. The Ethernet traffic bandwidth is
optimized by GFP-F encapsulation and VC-12-Xv virtual concatenation using LCAS.
