Configure the type of DSL operating mode for the ATM-over-ADSL
interface—for example auto.
Annex A and Annex B support the following operating modes:
- auto—Configures the ADSL interface to autonegotiate
settings with the DSLAM located at the central office. For Annex A,
the ADSL interface trains in either ANSI T1.413 Issue II
mode or ITU G.992.1 mode. For Annex B, the ADSL interface
trains in ITU G.992.1 mode.
- itu-dmt—Configures the ADSL interface to
train in ITU G.992.1 mode.
Annex A supports the following operating modes:
- adsl2plus—Configures the ADSL interface
to train in ITU G.992.5 mode. You can configure this mode only when
it is supported on the DSLAM.
- itu-dmt-bis—Configures the ADSL interface
to train in ITU G.992.3 mode. You can configure this mode only when
it is supported on the DSLAM.
- ansi-dmt—Configures the ADSL interface
to train in the ANSI T1.413 Issue II mode.
Annex B supports the following operating modes:
- etsi—Configures the ADSL line to train
in the ETSI TS 101 388 V1.3.1 mode.
- itu-annexb-ur2—Configures the ADSL line
to train in the G.992.1 Deutsche Telekom UR-2 mode.
- itu-annexb-non-ur2—Configures the ADSL
line to train in the G.992.1 Non-UR-2 mode.
|
- Next to Dsl options, click Configure.
- From the Operating Mode list, select auto.
- Click OK.
|
Enter
set dsl-options operating-mode auto

Configure the encapsulation type—for example, ethernet-over-atm.
- atm-pvc—ATM permanent virtual circuits
is the default encapsulation for ATM-over-ADSL interfaces.
For PPP over ATM (PPPoA) over ADSL interfaces, use this type
of encapsulation.
- ethernet-over-atm—Ethernet over ATM encapsulation.
For PPP over Ethernet (PPPoE) over ATM-over-ADSL interfaces
that carry IPv4 traffic, use this type of encapsulation.
|
From the Encapsulation list, select ethernet-over-atm.
|
Enter
set encapsulation ethernet-over-atm

Logical Properties |
Add the logical interface.
Set a value from 0 and 16385—for example, 3.
Add other values if required by your network.
|
- Scroll down the page to Unit, and click Add new entry.
- In the Interface unit number box, type 3.

Configure encapsulation for the ATM-for-ADSL logical unit—for
example, atm-nlpid.
The following encapsulations are supported on the ATM-over-ADSL
interfaces that use inet (IP) protocols only:
- atm-vc-mux–Use ATM virtual circuit multiplex
encapsulation.
- atm-nlpid–Use ATM network layer protocol
identifier (NLPID) encapsulation.
- atm-cisco-nlpid–Use Cisco NLPID encapsulation.
- ether-over-atm-llc–For interfaces that
carry IPv4 traffic, use Ethernet over LLC encapsulation. You cannot
configure multipoint interfaces if you use this type of encapsulation.
The following encapsulations are supported on the ATM-over-ADSL
for PPP-over-ATM (PPPoA) interfaces only. (For a sample PPPoA configuration,
see Verifying Interface Configuration.)
- atm-ppp-llc— AAL5 logical link control
(LLC) encapsulation.
- atm-ppp-vc-mux—Use AAL5 multiplex encapsulation.
Other encapsulation types supported on the ATM-over-ADSL interfaces:
- ppp-over-ether-over-atm-llc—Use PPP over
Ethernet over ATM LLC encapsulation. When you use this encapsulation
type, you cannot configure the interface address. Instead you configure
the interface address on the PPP interface.
- atm-snap—Use ATM subnetwork attachment
point (SNAP) encapsulation.
