the other link end you will receive these packets to be dealt with by the IP-router, provided
you set the same SVLAN number for reception.
SVLAN with number 0 differs from others by that traffic through it is transmitted without
additional headers at all, thus providing the highest transmission efficiency. The rest SVLAN
(1-1020) add two bytes to each packet.
Into one SVLAN one can, using router facilities, route the required number of networks,
each of them having its own priority level.
2.8.2 IP-router
UHP-1000 routers implement a standard IP-router supporting static routing. The routing
table can contain the following records:
IP-address on LAN
Statistical route in the LAN direction
IP-map – a route to the modulator in SVLAN
SVLAN Receive – a command to receive SVLAN from one of the demodulators
Records in the Table are arranged according to the network mask. The first ones are records
with mask /32. Any of the records can contain VLAN and then it is referred to the Table of
the relevant VLAN and will work only in it.
Altogether, the Table can contain up to 1,000 records. Routing speed is practically
independent of the number of records.

Figure 17 Routing layout with examples of commands
Records to the route Table come from two sources – local settings and the routing table
received from the Hub. Routes from Hub are always entered in the routing table. Local
configuration routes are entered only if it is permitted from Hub or if routers routing remote
control system is switched off on Hub. On Hub, you can allow or prohibit, for each individual
router, reception of various routing records from the local configuration. For example, you
can allow local administrator of the router add static routes but prohibit changing IP-
addresses and SVLAN.
All records are provided with counters of packets that have been routed as per these
records. This will make diagnostics easier.
UHP-1000 router has no limitations on overlapping the addresses, incompliance of masks,
etc. This makes it possible to obtain more capabilities from routers but these capabilities
should be used with care.
