When providing the T.30 FAX communication the PN-32IPLA-A IP PAD-D/E card
and the PN-16VCTAA IP PAD-B are required.
2.9.3 Modem over IP, Pass-through mode between 8IPLA IP-PADs (R9)
With R9 software and SPN-8IPLA PAD-B the system detects the modem connection and
uses pass-through mode for better through put and success rate. Connection speeds range
from 9.6 kbps to 24 kbps; those speeds vary depending on the CODEC used (G.711 or
G.726) and network configuration.
Required Hardware: SPN-8IPLA IP PAD-B
2.10IP networking
2.10.1 MP, IP-PAD LAN interface speed setting enhancement to
100Mbps/full duplex mode(fixed) (R9)
R9 software adds fixed 100 Mbps Full Duplex to the CPU/M606, which is adjusted via
office data programming.
Control for 100 Mbps Full Duplex or auto-negotiate 10/100 Half Duplex on the 32 IPLA
and 8 IPLA IP PAD is done via switch settings on each card.
Required Hardware:
-
SPN-8IPLA IP PAD-A/B with SC-3330 Firmware
-
SPN-32IPLAA IP PAD-C/D/E with SC-3353 Firmware
2.10.2 VLAN Tagging
The SOPHO 2000 IPS supports VLAN-based on IEEE 802.1Q (Tag VLAN) to logically
separate “voice”-data from the other traffic on the LAN/WAN. VLAN lessens the
possibility of packet collision and prevents voice quality degradation from lack of
available bandwidth.
2.10.3 NAT support (R12.1)
This feature provides efficient use of global IP addresses and better security that shields
internal addresses from the public Internet).
NAT (Network Address Translation) is a technology that translates the internal local IP
addresses to globally unique IP addresses before sending packets to the outside network.
NAT is configured on the router at the border of the inside network and the outside
network. NAT is used for efficient use of global IP addresses and for security (shield
internal addresses from the public Internet). In R12.1 software, the 2000 IPS support
network configuration via a router with NAT.
