Click on the Transmit PRM box. Choices of
N
O
and
Y
ES
will appear. Enabling the performance
report messages (PRM) allows the unit to send messages across the facility data link (FDL) per
ANSI T1.403. The terminating device at the Telco may use this information for management of the
T1 loop. The IQ 710 supports PRM messages per AT&T Pub 54016, which is a poll/response type
protocol. Because of the poll/response nature, the transmit PRM option does not disable the
IQ 710 from processing or responding to 54016-type messages. For this example, it is assumed all
three sites set transmit PRM to
Y
ES
.

Click on the Clock Source box. Choices of
I
NTERNAL
and
F
ROM
N
ETWORK
will appear. Use the
arrow keys to select
F
ROM
N
ETWORK
if the Telco is providing clocking on the T1 line. Select
I
NTER
-
NAL
if there is no timing on the T1 circuit and the IQ 710 will have to provide the clock. For this
example, it is assumed all three sites will take clocking from the network.
11.
Click on the Number of Channels box. Enter the total number of channels for the Telco-provided
T1 line. If a full T1 circuit was purchased, the number of channels will be 24. If a fractional T1 cir-
cuit was purchased, the number of channels can be obtained from the TELCO. In this example, all
three sites have a different number of channels. This step is only valid for the T1/FT1 Network
Interface Card. If a T1/FT1+DSX-1 Network Interface Card is used, the DSO Map will be different.
12.
Click on the Start Channel box. Enter the first DS0 number available for the Telco-provided T1
line. If a full T1 was purchased, the start channel will be one. If a fractional T1 circuit was pur-
chased, the start channel information can be obtained from the Telco. For this example, it is
assumed all three sites have a start channel of one. This step is only valid for the T1/FT1 Network
Interface Card. If a T1/FT1+DSX-1 Network Interface Card is used, the DSO Map will be different.
13.
Click on the Channel Alignment box. Choices of
C
ONTIGUOUS
or
A
LTERNATING
will appear. Select
the alignment that matches the alignment on the Telco-provided T1 line. For this example, it is
assumed all three sites have contiguous channel alignment. This step is only valid for the T1/FT1
Network Interface Card. If a T1/FT1+DSX-1 Network Interface Card is used, the DSO Map will be
different.
14.
Click on the Frame Relay Signaling Type box. Choices of
N
ONE
, LMI, ANSI T1.617-D, ITU-T
Q.933-A
, and
A
UTO
will appear. Select the signal type that matches the signal type on the Telco-
provided T1 line. For this example, it is assumed that the frame relay network switch is using ANSI
T1.617-D signaling to all three sites.
15.
Click on the Management DLCI #1 and Management DLCI #2 boxes. These DLCIs are used to
carry management traffic to and from the network. Since management is not part of this example,
this parameter should be left at the default value for all three units.
16.
Click on the DLCI #1 Mode and DLCI #2 Mode boxes. Choices of
D
EDICATED
and
S
HARED
will appear.
Set to
D
EDICATED
if the management DLCI is used only to manage the IQ 710 and not used to carry
customer traffic. If set to
D
EDICATED
, the router is not notified of that DLCI. Set to
S
HARED
if the man-
agement DLCI is used for carrying customer traffic and management data. Since management is not
part of this example, this parameter should be left at the default value for all three units.
17.
Click on the LMI Integrity Poll Timer, T391 box. This is the time in seconds between polls to the
frame relay network. The default value of
10
is sufficient for most networks.
18.
Click on the LMI Status Polling Counter, N391. This is the number of link integrity polls which occur
in between full status polls. The default value of
6
is sufficient for most networks.
19.
Click on the Error Threshold, N392 and Error Window, N393 boxes. These parameters define the error
threshold for the User-to-Network Interface (UNI) formed by the IQ 710 network port and the frame
