Nokia M5122 User Manual

maximum transmit rate on the VCC is equal to the ADSL upstream capability.

The ADSL transmission is based on the DMT line code. M5122 provides a DMT line rate up to 8 Mbit/s downstream and up to 800 kbit/s upstream. The DMT transceiver is rate adaptive and capable of providing faster rates over short distances or slower rates over long distances. The transceiver adapts itself to the line conditions and rate adaptation is done in steps of 32 kbit/s. The network operator can set the data rates as a part of the network management functionality provided by Nokia DSLAM.

M5122 supports ATM over ADSL transmission ITU-T G.992.1 and ADSL Lite ITU-T G.992.2. The ADSL mode can be changed through the command line interface.

4.3Dynamic Host Configuration Protocol

Note

Use DHCP with PPTP tunneling only.

M5122 can act as a Dynamic Host Configuration Protocol (DHCP) server for the PCs on the end-user home network. In this mode, M5122 can assign up to 253+253 consecutive addresses from two separate address ranges (that is, 253 consecutive addresses per address range) to the PCs on the home network. Two separate address ranges can be used if more than 253 addresses are required on the local subnet, if two non-contiguous address ranges are needed or if an additional router with DHCP relay is used on the local network. M5122 can also act as a DHCP relay agent and relay the DHCP requests to an external DHCP server.

4.4Point-to-Point Tunneling Protocol (PPTP)

When PPTP local tunneling is used, a local network client initialises a PPTP-tunneled PPP connection (VPN) to Nokia M5122. The modem terminates the tunnel and all data from that terminated local PPTP tunnel will be forwarded to an assigned ATM VCC by using PPP over AAL5 encapsulation. Thus, each local PPTP tunnel requires an equivalent ATM VCC assigned to it restricting the total number of local PPTP hosts to 8.
