1.1 Interface Types
Interfaces on the router are used to exchange data and interact with other network devices, and
are classified into physical interfaces and logical interfaces.
Physical Interfaces
Physical interfaces exist on boards.
Physical interfaces are classified into the following types:
lLAN-side interface: is used by the router to exchange data with network devices on LANs.
lWAN-side interface: is used by the router to exchange data with devices on external
networks.
Table 1-1 Physical interface types
Type Sub-type Description
LAN-side
interface
Fast Ethernet (FE)
interface
A LAN-side FE interface works at the data link
layer, provides a maximum of 100 Mbit/s
transmission rate, processes Layer 2 protocol
packets, and implements Layer 2 forwarding.
Gigabit Ethernet (GE)
interface
A LAN-side GE interface works at the data link
layer, provides a maximum of 1000 Mbit/s
transmission rate, processes Layer 2 protocol
packets, and implements Layer 2 forwarding.
WAN-side
interface
FE interface A WAN-side FE interface works at the network
layer, can be assigned an IP address, provides a
maximum of 100 Mbit/s transmission rate,
processes Layer 3 protocol packets, and provides
the routing function.
GE interface A WAN-side GE interface works at the network
layer, can be assigned an IP address, provides a
maximum of 1000 Mbit/s transmission rate,
processes Layer 3 protocol packets, and provides
the routing function.
CE1/CT1 interface A CE1/CT1 interface is a channelized E1/T1
interface. It can be assigned an IP address,
processes Layer 3 protocol packets, has the same
logical interfaces as a synchronous serial
interface, works in different modes, and supports
Point-to-Point (PPP), Frame Relay (FR), and
Integrated Services Digital Network (ISDN).

Type Sub-type Description
Synchronous/
Asynchronous serial
(SA) interface
An SA interface can work in synchronous mode
as a synchronous serial interface or in
asynchronous mode as an asynchronous serial
interface. Link layer protocols such as PPP and
FR can be configured on synchronous serial
interfaces. Parameters such as the stop bit and
data bit can be set on asynchronous serial
interfaces.
Async Interface An async interface is used as a synchronous
serial interface. The link layer protocol is PPP
when async interfaces work in protocol mode.
Parameters such as the stop bit and data bit can
be set on asynchronous serial interfaces.
Asymmetric Digital
Subscriber Line (ADSL)
interface
An ADSL interface provides asymmetric
transmit and receive rates and implements fast
data transmission over copper twisted pairs by
employing high frequencies that are not used by
regular telephone lines.
G.Single-pair High-
speed Digital Subscriber
Line (G.SHDSL)
interface
A G.SHDSL interface provides symmetric
transmit and receive rates and implements fast
data transmission over copper twisted pairs by
employing high frequencies that are not used by
regular telephone lines.
3G CellularInterface The 3G Cellular interfaces are used to configure
and maintain the 3G modems connected to the
router. The link layer protocol is PPP and the
network layer protocol is IP.
E1-F/T1-F interface An E1-F/T1-F interface is an E1/T1 interface
working in fractional channelized mode. It is a
simplified CE1/PRI or CT1/PRI interface. To
reduce costs, E1-F/T1-F interfaces can be used
in E1/T1 access scenario.
ISDN BRI interface A BRI interface contains two 64 kbit/s B
channels and one 16 kbit/s D channel, and the
interface bandwidth is 2B + D. Link layer
protocols such as PPP and FR can be configured
on ISDN BRI interfaces and the network layer
protocol is IP.
CPOS interface Making full use of the SDH system, Channelized
POS (CPOS) interfaces are mainly used to
improve the convergence capability of low-
speed access for routers.

Type Sub-type Description
Voice Interfaces Voice Interfaces are classified into the following
interfaces:
lAn FXS interface connects to a POTS phone.
To achieve high transmission efficiency on
an FXS interface, properly set parameters for
the FXS interface on the AR1200, including
physical attributes, electrical attributes, and
KC attributes.
lAn FXO interface connects to a PSTN. To
achieve high transmission efficiency on an
FXO interface, properly set parameters for
the FXO interface on the AR1200, including
the gain, impedance, ring current, and feed.
lA basic rate access (BRA) interface connects
to an ISDN phone. On the AR1200, you can
enable the BRA interface Layer 2
monitoring, remote power supply, automatic
deactivation, and alarm functions, and set the
working mode and Layer 1 activation mode
on a BRA interface.
lA VE1 interface connects to a PBX or PSTN
network. On the AR1200, you can enable the

Type Sub-type Description
WLAN-BSS interface A WLAN-BSS interface is a virtual Layer 2
interface. Similar to a Layer 2 Ethernet interface
of the access type, a WLAN-BSS interface has
Layer 2 attributes and supports multiple Layer 2
protocols.
1.2 Interface Numbering
This section describes the interface numbering scheme on the AR routers.
On the AR routers, interfaces are numbered in the format of slot ID/subcard ID/interface
sequence number.
lSlot ID
The slot ID specifies the ID of the slot where a card resides.
–The SRU of the AR1200 and 2220 is integrated with the chassis, so the slot ID is fixed
as 0.
–When slots need to be combined into one slot, the greater slot ID is used as the new slot
ID. For example, when slot 1 and slot 2 are combined, slot ID 2 is used as the new slot
ID.
lSubcard ID
The subcard ID specifies the ID of a subcard. The cards of AR routers series routers do not
support subcards. Therefore, the subcard ID of the AR routers is fixed as 0.
lInterface sequence number
The interface sequence number indicates the number of each interface on a card.
–There is only one row of interfaces on the interface card. These interfaces are numbered
from left to right starting with 0.
0 1 2 3
–There are two rows of interfaces on the interface card. These interfaces are numbered
from bottom to top and left to right starting with 0.
