Page 38: Automatic Transmission Level Control (Tlc) For Scpc
SVLAN overview UHP-1000 routers make use of a special protocol to transmit information via the satellite. Requirements to such protocol are minimal overhead and a possibility to split and group data streams. With the UHP-1000 routers, this protocol is named SVLAN. -
Page 39: Router Control Commands
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. - Page 40 UHP-1000 SATELLITE ROUTER INSTALLATION AND OPERATION MANUAL, V. 2.5 (SW VERSION 2.5.X) ip delete IP_ADDR IP_MASK [1-1020] - Delete IP address, route or map [VLAN] Delete address, route or map. svlan delete demod|tdma 0-1020 [1-1020] - Delete SVLAN [VLAN] Delete record on SVLAN reception.
