16.17.3 Integrated Service Access
The example in Figure
a typical integrated service access scenario, where different service
providers are accessed via permanent virtual circuits (PVCs) on Frame Relay over the serial interface of
a SmartNode 2300 series device.
The multi service provider (MSP) offers both Internet access and voice services based on IP. The virtual
private network (VPN) provider offers secure interconnections of local access networks (LAN) via its
public wide are network based on IP. Since both providers are working independently the SmartNode
2300 series device needs a configuration, which has two dedicated PVCs on Frame Relay. The first PVC,
labeled as PVC 1, connects to the MSP access device. The second PVC, labeled PVC 2, connects to the
VPN provider access device on the leased line network.
A SmartNode 2300 series device is working as a DTE and accesses the leased line network via a leased
line modem connected to the serial interface. On the serial interface on slot 0 and port 0 the hardware
port protocol X.21 is used.

Figure
Typical Integrated Service Access Scenario with dedicated PVCs
Devices accessing the MSP and VPN services are attached to the 100 Mbit/s Ethernet port 0/0 on the
SmartNode 2300 series device. For that reason an IP context with three logical IP interfaces bound to
Ethernet port 0/0, PVC 1 and PVC 2 on serial port 0/0 as shown in Figure 16-3 has to be configured for
the SmartNode 2300 series device. The IP interfaces are labeled to represent the function of their
configuration. Hence Ethernet port 0/0 is named
lan
, PVC 1 is named
external
since external services are
accessed via this PVC, and PVC 2 is named
internal
to indicate the private network interconnection via
this PVC.
