Conversely a "specified location" can be set which restricts remote access from only that location, this specified
location can also be a designated dial back number thereby minimizing the threat of unauthorized remote
access.
IP Office systems can also incorporate remote access dial back services so that if a user always remotely
accesses the office from a single location e.g. their home, then after login verification the system will disconnect
their call and dial them back. In addition to the added level of security dial back provides it can also be an
excellent method of consolidating remote access charges onto the central office telephone bill.
In addition to remote access from Telephone Adaptors, all ATM4 trunk cards (including the IP500 V2
Combination Card ATM) support switching of the first analog trunk to an integral V.32 modem for remote
access.
LAN to LAN Routing
All businesses now have a need for data routing whether it's a requirement to share resources such as email
servers, file servers and internet gateways, or seamlessly transport data between sites or network to and from
their customers and suppliers. This is why each IP Office platform offers IP routing as standard.
Embedding a router within IP Office removes the costs, complexity and additional points of failure of external
WAN multiplexers by allowing data and voice traffic to converge and share the network resources of IP Office.
These network resources can range from dial up ISDN connections, point-to-point leased circuits, managed IP
networks or Frame Relay as IP Office supports all these types of network connections.
Data Networking Features
Integral 10/100 Mbit Layer 3 Ethernet Switch
Layer 3 switching is particularly useful in situations where it is desirable to have a ‘trusted’ and ‘unsecured’
network, where the ‘unsecured’ network is uncontrolled and carries public traffic on it.
It is possible to set up a firewall between two LAN segments using the IP Office layer 3 switch. IP500 V2
supports a two-port Layer 3 Ethernet switch with the firewall between them. Both of these switched ports have
their own IP addresses (LAN1 and LAN2) and in order for traffic to pass from one port to the other, a route is
configured in the system’s routing tables.
DHCP Server
IP Office can manage your IP Network for you through its integral DHCP Server. IP Office can be configured to
hold a pool of IP addresses for users on the Local Area Network. When a user powers up their PC, the system
will allocate them an IP address for the duration of their session. The DHCP server also provides the user's PC
with the address of the Domain Name Service (DNS) server and the Windows Name Service (WINS) server.
Alternatively, for customers who have a separate DHCP Server, IP Office can be configured to obtain its address
from that DHCP server or be set with its own static IP address. Both IP500 and IP500 V2 have two independent
DHCP servers, one dedicated to each of the Layer 3 switched LANs.
Leased Line Support
IP Office is capable of connecting to leased line services.
IP Office WAN services are supported over E1/T1 PRI trunks and BRI trunks. E1/T1 trunks can be configured to
operate in a fractional mode for 'point to multi-point' applications i.e. a single 2M interface could be treated as 3
x 512K and 8 x 64K going to 11 different locations. When using T1 as a Leased Line it is possible to use the
same circuit for switched circuit services. Not all types of leased line are available in all territories, check for
availability.
Dial-Up Circuit Support
Where the amount of traffic does not justify the cost of a dedicated leased line, the system can provide data
connectivity via ISDN dial-up circuits using its E1/T1 or Basic Rate trunks. Where data speeds greater than a
single channel are required (64K/56K), additional channels can be added to the call as and when they are
needed.
Point-to-Point Protocol (PPP)
PPP is an industry standard Wide Area Networking Protocol, that allows inter-working with a wide range of 3rd
party routers. PPP is used over leased line circuits where a single channel is used to connect the two locations
together. e.g. A single channel maybe a 64K channel on a dial-up circuit or a 256K leased line etc.
