Configure the
L2 P

parameters and view the status of the T1 interface using items from this menu.
L2 P

(T1 ATM – T1) > P
ROTOCOL
Configure the
L2 P
ROTOCOL
mode. Choices are
ATM
and
C
U
MTN
(def). Selecting
ATM
configures the
interface for Asynchronous Transfer Mode signaling on Layer 2. Selecting
C
U
MTN
configures the
interface for Copper Mountain frame relay signaling on Layer 2.

Asynchronous Transfer Mode allocates bandwidth on demand, automatically adjusting the network
capacity to meet the system needs. Fixed-length cells (53 octet) require lower processing overhead and
allow higher transmission speeds than traditional packet switching methods. ATM uses five octet headers
in each fifty-three octet cell to match cells with specific virtual channels to which they belong.

Copper Mountain Frame Relay is a data link layer protocol that uses Frame Relay instead of ATM on the
subscriber loop. Frame relay is a switched layer protocol that handles virtual circuits using High-Level
Data Link Control (HDLC) encapsulation. Frame Relay uses statistical multiplexing as opposed to
time-division-multiplexing many logical connections over a single physical link.

format must be configured for either
ATM F
ORUM
(U

)
or
ITU (I

. Configuring
this setting incorrectly for a particular circuit will cause poor performance at the ATM Layer. The default
is
ATM F
