IPR 10B2 and 10BT Cards Description (883060/883160)
The IPR 10B2 and IPR 10BT cards are functionality the same card except the IPR 10B2 has
an Ethernet interface port and uses a coax jack for a 10Base-2 connection and the IPR 10BT
card has an Ethernet interface port and uses a modular jack for a 10Base-T connection (RJ48).
an Ethernet interface port and uses a coax jack for a 10Base-2 connection and the IPR 10BT
card has an Ethernet interface port and uses a modular jack for a 10Base-T connection (RJ48).
The IPR 10B2 and 10BT Cards are IPR routers that route packets based on IP destination
address. IPR routes IP datagrams between Ethernet and Frame Relay PVCs. Frame Relay
PVCs can be associated with any of the three Frame Relay ports. IPR also has provisions to
automatically forward IP packets to and from the host (CPU) IP node of the Integrated Access
System that IPR resides in. It automatically takes care of all the IP fragmentation to and from
the host (CPU) IP node.

IPRs can also be optionally connected to FRS server card (on the same Integrated Access
System), giving the option of concentrating Ethernet traffic in addition to other ports of
concentration on the FRS card. The maximum number of bytes that an IPR can handle in a
single packet is 1520 bytes regardless whether a packet arrives from Ethernet or Frame Relay
interface.

IPR supports SNMP for Ethernet, Frame Relay, IP and Routing MIBs. It uses the standard
Ethernet encapsulation, utilizing 14 bytes Ethernet Header: Source Ethernet Address (6
bytes), Destination Ethernet Address (6 bytes), and a Protocol Type (2 bytes). IPR supports
RIP (Routing Information Protocol, RFC 1058) for dynamically discovering IP routes from
adjacent IP routers on Frame Relay or Ethernet.

The use of simple filtering and forwarding decisions based on the physical layer address
allows less processing time per packet. Because of this, bridging provides better WAN
bandwidth, compared to routing. IPR will forward packets matching an entry in the MAC
addresses table, configured manually by the user.
