In this field the lower section of the security layer (Data Link Layer) is configured.
Telnet path: /Setup/WAN/Layer
Possible values:
- AAL-5: ATM adaptation layer
- ETH: Transparent Ethernet as per IEEE 802.3.
- HDLC64K: Securing and synchronization of data transmission as per HDLC (in 7 or 8-bit mode).
- HDLC56K: Securing and synchronization of data transmission as per HDLC (in 7 or 8-bit mode).
- V110_9K6: Transmission as per V.110 at max. 9,600 bps, e.g. for dialing in by HSCSD mobile phone
- V110_19K2: Transmission as per V.110 at max. 19,200 bps
- V110_38K4: Transmission as per V.110 at max. 38,400 bps
- Serial: For connections by analog modem or cellular modem with AT interface. The modem can be connected to the device at its serial interface (outband) or to a USB interface by means of a USB-to-serial adapter. Some models feature a CardBus slot that accommodates suitable cards. Some models have an internal integrated modem.
- Modem: For connections via the internal modem emulation when operating as a V.90 host modem over ISDN. Operation of the internal modem may require an additional software option for the device.
- VDSL: VDSL2 data transmission as per ITU G.993.2
Default: HDLC64K
Note: The range of available values depends on the hardware model at hand.
