Error Messages Shows you that the logging of error or warning messages into the 
Windows NT Event Viewer is on. Display-only.
When this option is on, you can use the Windows NT Event Viewer 
to view the reported errors and warnings. (In this release, the Log 
Properties option is not available for this log.)
Performance 
StatisticsAllows you to turn logging of QoS (quality of service) statistics on 
or off. The statistics are logged into the Windows NT Performance 
Monitor. (In this release, the Log Properties option is not available 
for this log.)
Log Properties Allows you to set the maximum log file size. 
Valid values: 
1 to 100 (MB).
When a log file reaches this setting, the DEFINITY ECS 
application will create a new log file. In addition, for the CDR log 
only, this properties window allows additional CDR file 
management. If this feature is checked, then a copy of the CDR file 
is maintained. This allows a remote client to retrieve the CDR 
records from the DEFINITY ECS application periodically, without 
affecting the operation of the application. This feature makes two 
additional parameters available:
nWrite file every  minutes: Specifies how often the copy 
file is refreshed. If the file doesn’t exist, then it is created. 
Valid values: 
1 to 60. 
nLocation: Specifies the directory where the copy (alternate) 
CDR file is stored.

QoS dialog box
Use the Quality of Service (QoS) dialog box to configure the quality of service 
options for the DEFINITY ECS connections to remote sites.
The Quality of Service dialog box contains the following parameters:
Parameter Description
Line Pool ID Allows you to specify an integer between 1 and 999 that identifies a 
logical group (pool) of lines. The lines consist of trunk groups that 
emulate T1 (robbed-bit) or E1 (common-channel) channels. No 
ISDN connections can be placed in the trunk groups that make up 
line pools. This line pool is used to handle calls to a particular remote 
site. 
Highlight a Line Pool ID (number) and click on 
Properties (shows 
statistics):
nIdle - do not monitor QoS
nMonitor only - monitor QoS and do not take trunks out of service
nMonitor - PSTN Fallback - monitor QoS and take trunks out of 
service if QoS is below thresholds
Remote IP 
AddressAllows you to specify the IP address of the remote site whose calls 
will be handled by this pool.
Lines in Pool Allows you to specify which trunk groups are members of this line 
pool.

QoS ParametersnSampling Interval (sec): Allows you to specify how often the 
quality of service to the highlighted line pool’s remote IP address 
will be checked. 
Valid values: 
1 to 300 (seconds). 
nSamples to Average (number): Allows you to specify the 
number of samples to average together when evaluating the 
quality of service to this remote site.
Valid values: 
5 to 1500.
nPacket Loss Threshold (%): Allows you to specify the 
acceptable level of percentage of packets lost when evaluating 
the quality of service to this remote site. When the PSTN 
Fallback option is set and the threshold reaches high, the 
DEFINITY ECS application disables all the lines in this pool. 
This causes subsequent calls to be routed over the PSTN 
(assuming the switch is correctly configured), instead of the IP 
network.
nLow: Valid values: 0 to 100.
nHigh: Valid values: 0 to 100.
nRound Trip Delay Threshold (msec.): Allows you to specify 
the acceptable level of round trip delay in milliseconds when 
evaluating the quality of service to this remote site.
nLow: Valid values: 10 to 1500.
nHigh: Valid values: 10 to 1500.
The algorithm for the Packet Loss Threshold and Round Trip 
Delay Threshold evaluations works as follows:
nIf either high value is exceeded, the line pool is blocked.
nAfter the averaged evaluation is below both of the low values, 
the line pool is unblocked.
Add Allows you to add line pools.
Remove Allows you to remove line pools.
Edit Allows you to edit line pools.
Clear All Clears all the information from the Line Pools section of the QoS 
dialog box.

ISDN trunk group
This screen assigns an Integrated Services Digital Network (ISDN) trunk group 
that supports the ISDN and Call-by-Call Service Selection service selection 
features. The trunk group provides end-to-end digital connectivity and supports a 
wide range of services including voice and non-voice services, to which users 
have access by a limited set of CCITT-defined, standard multipurpose interfaces.
The ISDN trunk group may contain ISDN-PRI or ISDN-BRI interfaces. However, 
it is not possible to use the two types of interfaces in the same trunk groups. The 
type of interface is chosen when the trunk members are assigned to the trunk 
group.
When ISDN-PRI interfaces are used on ISDN trunk groups, they may also be used 
to support the Wideband Switching feature. This is intended to work with the H0 
(384 Kbps), H11 (1536 Kbps), H12 (1920 Kbps), and NXDS0 (128 to 1984 Kbps) 
data services, and to support high-speed video conferencing and data applications.
Administration commands
When an ISDN trunk connects two switches, set the trunk options identically at 
both ends of the connection, with the exception of the Trunk Hunt fields. When 
ISDN-PRI interfaces are used, it is acceptable for both ends to have the  Trunk 
Hunt fields administered as 
cyclical, but if one end is administered as ascend, the 
other end must be administered as 
descend. This helps avoid the possibility of 
glare conditions. When ISDN-BRI is used, the Trunk Hunt field has to be 
cyclical.

Hardware requirements
ISDN-BRI interfaces are supported by the TN2185 Trunk-side BRI circuit pack 
(for implementing the user side of the BRI interface) and by the TN556B or 
TN556C ISDN-BRI Line circuit pack or the TN2198 ISDN BRI (U-LT) Line 
circuit pack (for the network side of the BRI interface). The TN2464 circuit 
supports T1 and E1 digital facilities.
ISDN-PRI interfaces are supported by the TN767 circuit pack (for assignment of a 
T1 signaling link and up to 24 ISDN-PRI trunk group members), or the TN464C 
or later circuit pack (for assignment of a T1 or E1 signaling link and up to 24 or 31 
ISDN-PRI trunk group members, respectively). The TN2464 and TN2207 circuit 
pack can also be used with ISDN-PRI.
nFor R7si and later configurations and R7csi and later configurations, the 
D-channel for ISDN-PRI interfaces switches through either the TN765 
Processor Interface (PI) circuit pack or the TN778 Packet Control 
(PACCON) circuit pack. The D-channel for ISDN-BRI interfaces only 
switches through the TN778 Packet Control (PACCON) circuit pack.
NOTE:
You cannot use the TN765 circuit pack with ISDN-BRI interfaces.
nFor R7r and later configurations, the D-channel switches through the 
TN1655 Packet Interface (PKTINT) circuit pack.
nA TN780 or TN2182 Tone Clock circuit pack provides synchronization for 
the DS1 circuit pack. 
NOTE:
The TN767 cannot be used to carry the D-channel if either the TN778 
(PACCON) or TN1655 (PKTINT) circuit packs are used to switch 
the D-channel. However, in these circumstances, the TN767 can be 
used for NFAS interfaces carrying only B-channels.

nISDN-BRI Trunk Circuit Pack — This screen is required if using 
ISDN-BRI trunk interfaces. Assign all fields as required.
nDS1 Circuit Pack — This screen is required if using ISDN-PRI interfaces.
— DS1 (T1) Circuit Pack
Assign all fields as required. For Facility Associated Signaling, up 
to 23 ports are available for administration as trunk members in an 
associated ISDN-PRI trunk group. The 24th port is used as a 
signaling channel. For Non-Facility Associated Signaling, all 24 
ports may be used on certain DS1 circuit packs. The D-channel 
signaling function for these packs must be provided by a designated 
DS1 pack on its 24th channel.
— E1 Circuit Pack
Assign all fields as required. For Facility Associated Signaling, up 
to 30 ports are available for administration as trunk members in an 
associated ISDN-PRI trunk group. Port number 16 is used as a 
signaling channel.
nMaintenance-Related System-Parameters — Use this screen only for a 
TN778. Set the Packet Bus Maint field to 
y.
nISDN Trunk Group — Enter information in all the fields except the trunk 
group members. When using ISDN-PRI interfaces, enter the members after 
you establish the signaling links.
nSignaling Group — This screen is required if ISDN-PRI interfaces are 
used. Complete all fields. This screen identifies groups of ISDN-PRI DS1 
interface B-channels for which a given D-channel (or D-channel pair) will 
carry the associated signaling information (supports the Facility and 
Non-Facility Associated Signaling feature). Each DS1 board that is 
required to have a D-channel must be in a different signaling group by 
itself (unless D-channel backup is needed, in which case a second DS1 is 
administered as a backup D-channel). You are not required to select a 
channel for a trunk group, but if you do, you must have already defined the 
trunk group as type ISDN.
NOTE:
The following three screens, Processor Interface Data Module, 
Communication Interface Links, and Communication Processor 
Channel Assignment are used only to support the ISDN-PRI 
interfaces using PI TN765.
