are declared. Reset when ETis reset.
SEVERE ERR SEC: Count of 1 second intervals during which at
least 50 CRCerrors aredeclared or 1 or more LOSW defects are

to a 30% error frame rate for a normal frame length. Reset when
ETis reset.

DISPLAY ALL EOC MESSAGES
• ON: will display far end values for CRC, SES, ES, UAS, and

(if available). At this time, the module does not support
this mode.
• OFF: is the default.
SNR MARGIN THRESHOLD
Adjust by using +1 (F1) or -1 (F2). The
threshold can be OFF, or
adjusted between -15 through +15 dB. If the SNR margin is less
than this setting, then the ALARM LED will be on.
LOOP ATTEN THRESHOLD
Adjust by using +1 (F1) or -1 (F2). The
threshold can be OFF, or
adjusted from 1–127. The default setting is OFF. If this setting is
exceeded, then the ALARM LED will be on.
RECEIVEEOC SNR OFFSET
For reporting via the EOC(for STU-C/R only).
• ON: for far end sending SNR raw values to near end.
• OFF: for farendsending SNR margin values to near end.OFF
is the default.
SEND EOC SNR OFFSET
For reporting via the EOC(for STU-C/R only).
• ON: for near end sending SNR margin values to far end. ON
is the default.
• OFF: for near end sending SNR raw values to far end.
TRANSFORMER RATIO
• ON: the transformer ratio is set to 5:4:1. ON is the default.
• OFF: the transformer ratio is set to 4:1.
CAUTION:
If the reported loop attenuation is significantly dif fer -

2.2.4 PING Setup/ Test
L i n k turn-up v e r i fi e s c o nn ec t i v i t y to a DSLAM. P I N G t e s t i n g t a k e s
the turn-up procedure one step further and verifies connectivity
to the far end network. PING is a common method to discover
whether two remote LAN segments using TCP-IP protocol are
connected. When receiving a PING message, Internet devices
acknowledge it by sending an echo message back.
After
t u r n i n g up the li n k , enter P I N G SETUP/TEST from the m o d -
ule main menu. The first screen contains configuration items for
the PING test. Enter the proper protocol used by the circuit, as
well as the necessary IP addresses. The first setting is MODE.
Notes:
• Before performing a PING test, confirm that the link is estab -
lished.
• To enter numbers,press SHIFT and use the numeric keypad.
If available, use <-,-> to move the cursor .

Select the protocol mode for the PING
test.
• PROFILE: Use to store and retrieve PING configurations, see
Section 2.2.4.4.
• LLC-BRG: LL C - B r i d g e p r o t o c o l . T h i s f o ll o w s RFC 1483 b r i d g e
encapsulation. It supports both static and dynamic IP man -
agement.
• LLC-RTE: LLC-Routed protocol. It supports only static IP
addr essing.
• CLIPoA: This refers to Classical IP over ATM according to
RFC2225. Used only in
STATIC mode.
• PPPoE: PPPover Ethernet,according to standard RFC 2516
PPPover Ethernet.
PPPoE supports dynamic IP addressing.
• PPPoA: PPP over ATM, according to standard RFC 2364, PPP
over AAL5. PPPoA supports dynamic IPaddressing.
The
actual configuration settings depend on the selected mode,
hence
the f o ll o w i n g s u b s ec t i o n s d e s c r i b e setup and P I N G r e s u l t s
for each mode.

VCI
Range:0 through 65535
The default is 35, which is a typical Ethernet assignment. Along
with VPI,
VCI identifies the next destination of a cell as it moves
through a series of ATM switches on the way to its destination.
Theservice provider typically assigns VCI.
IP ADDRESS
Options:
STATIC (F1), DHCP (F2)
• STATIC: This type of IP management meansthat the user has
a permanent IP address. For STATIC, enter the LOCAL IP; this
will be the value used during the test.
• DHCP: This refers to dynamic IP management. If selected,
enter the IP address for the destination.
D y n a m i c management p r o v i d e s a way for computers to o b t a i n
protocol configuration parameters (like the local IP address)
dynamically from the network. In this case, the IP address is
not permanent to the terminal; instead, the terminal requests
an
address from the server on the network. When selecting
DYNAMIC for IP ADDRESS, the module sends a request to
the server; the server responds and provides an IP addr ess.
Upon selecting DYNAMIC, the LOCAL IP line disappears; the
network dynamically
assigns an IP addr ess.
LOCAL IP
Enter a local IP address of the circuit under test. For LLC-BRG
static mode and LLC-RTE, this is the local IP address us
e d .
For LLC-BRG DHCP mode, there is no LOCAL IP mode since a
dynamically assigned local IP address is used.
DESTINATION IP
Enter the
destination address of the device to be pinged. If ping -
ing a gateway, enter the gateway’s address for the Destination
I P . Pinging the gateway verifies connectivity to the IS P .
GATEWAY
If required, enter a gateway address. A gateway is a device
that
connects dissimilar networks and passes information between
them. In TCP/IP, the default gateway address is the a dd r e ss
where the Internet
Protocolsends packets destined for r emote
networks, unless a different route is configured. Since LLC-RTE
is a pure routed mode, there is no gateway setting. This
setting
applies only to LLC-BRG mode.

After
c o n fi g u r i n g , press F3 to start the test. A s the testp r o cee d s ,
the test set displays an ‘IN PROGRESS’ message.
• The module will send 10 PINGs at one-second intervals.One
or more responses from the destination is considered a pass.
Refer to the following figure for a
pass sample.

• ‘PING PASS’ means the destination has received the PING
m e ss a g e a n d properly responded to t h e module. T hisin d i c a t e s
that the module can connect to the Internet.
• Ifthe test set receives noresponse,it will display ‘PINGFAIL’.
This indicates that either the destination did not receive the
PINGmessage or it did not reply.
• Press F4 to stop the test, press it again to restart testing.
• Press F1 to PING the DEST IP again after PING: PASS is
displayed.
In addition to the test results, the screen also r
eports:
ET: Elapsed Time since the test was started or restarted.
ST: Start Time of the
test.
LOCAL IP: Provides the local IP address for the module. For
LLC-BRG static and
LLC-RTE, this is the exact LOCAL IP a dd r e ss
entered i n the c o n fi g u r a t i o n screen. For LLC-BRG DHCP, LOCAL
IP shows all zeros until the DHCP server assigns an IP
addr ess.
When assigned, the LOCAL IP line will display this addr ess.
DEST IP: Provides the destination IPaddress for the
PING mes -
sages. This is determined in the configuration scr een.
