Sv8100 Netlink - NEC Univerge SV8100 Features And Specifications Manual

UNIVERGE SV8100
Enhancements
This feature added with Version 1100 (1.12 or higher).
With Version 4000 software, the failover process in a Netlink environment is improved. When
network communication is down, an alarm is sent to the Attendant terminal informing of the
communication error on the network. Improvements also allow for a defined number of network
outages per clock hour before failing over.
With Version 4000 software, DT700 terminals connected via NAPT can be registered to either the
primary or a secondary system in a NetLink environment.
With Version 5000 software, NetLink Multi-SIP carrier has been added.
With Version 7000 or higher software, the SV8100 can recognize each system where the DT700 extension(s)
are connected and provide an
NetLink.
With Version 9000 or higher software, an improvement has been made to NetLink to reduce the
number of packets transmitted over the network. The default value in Program 51-01-04 has been
changed to "Buffering". When set to "Buffering" small data packets are not transmitted immediately
across the network. The small data packets are buffered and sent via the network as one data
packet, therefore reducing network load, in one of the following conditions:
When an ACK Packet corresponding to the transmit packet is received.

When the data packet reaches the maximum segment size (1460bytes for Ethernet LAN and 1452bytes

for PPPoE).
When the time buffered exceeds 120ms.


Software Version 8000 and below use a timer of 250ms.
Description
The NetLink feature allows up to 16 sites to be linked together over a Data Communication IP NetLink
that allows Remote Sites to have the same service features as the Main Site, acting as one system.
Systems can be installed separately in the same building or in remote offices connected via a qualified
IP network.
With NetLink, the maximum system capacity still applies (200 Trunks and 512 Stations), but the ports
can be distributed between sites using an SV8100 CHS2U-US chassis at each location.
