M1112 has ALG forthe following protocols/applications: ICMP FTP H.323 including NetMeeting CUSeeMe PPTP IRC IPSEC ESP tunnel mode and IKENote, that most IPSEC implementations will fail when passed throughNAPT. A typical reason is that the identification may fail if theidentification is based on IP address. Also, only tunnel mode withoutAuthentication Header (AH) works.2.2.5 Dynamic Host Configuration ProtocolM1112 can act as a Dynamic Host Configuration Protocol (DHCP)server for the PCs on the end-user home network. In this mode, M1112can assign up to 253+253 consecutive addresses from two separateaddress ranges (that is, 253 consecutive addresses per address range)to the PCs on the home network. Two separate address ranges can beused if more than 253 addresses are required on the local subnet, if twonon-contiguous ranges are needed or if an additional router withDHCP relay is used on the local network. M1112 can also act as aDHCP relay agent and relay the DHCP requests to an external DHCPserver.2.2.6 ATM and ADSLM1112 supports up to 8 simultaneous VCCs and supports UBR(Unspecified bit rate) traffic shaping on all VCCs. The maximumtransmit rate on each VCC is the ADSL upstream capacity. If morethan one VCC is transmitting simultaneously, the ADSL upstreamcapacity is temporarily shared between these VCCs. When one VCC isidle, the bandwidth is used by another VCC.The ADSL transmission is based on the DMT line code. M1112provides a DMT line rate up to 8 Mbit/s downstream and up to 800kbit/s upstream. The DMT transceiver is rate adaptive and capable ofproviding faster rates over short distances or slower rates over longdistances. The transceiver adapts itself to the line conditions.M1112 is compatible with ETSI 101 388. |
