  Mediant 500L Gateway & E-SBC 
Parameter  Description 
overlap dialing mode. The device also plays a dial tone (for 
TimeForDialTone) until the next called number digits are 
received.  
  [2147483648] USER SCREEN INDICATOR = When the 
device receives two Calling Number IE's in the Setup 
message, the device, by default, uses only one of the 
numbers according to the following: 
  Network provided, Network provided - the first calling 
number is used 
  Network provided, User provided: the first one is used 
  User provided, Network provided: the second one is 
used 
  User provided, user provided: the first one is used 
When this bit is configured, the device behaves as follows: 
  Network provided, Network provided: the first calling 
number is used 
  Network provided, User provided: the second one is 
used 
  User provided, Network provided: the first one is used 
  User provided, user provided: the first one is used 
Note: 
 
In the Web interface, the parameter displays the summation 
of the enabled optional bit values, in hex format. For 
example, the default value is 0x11000 (69632 in decimal), 
which is the summation of the two bit options, USER 
SETUP ACK (0x01000 or 4096 in decimal) and PROGR 
IND IN SETUP ACK (0x10000 or 65536 in decimal) that are 
enabled by default (i.e., 4096 + 65536 = 69632). 
  When using the ini file to configure the device to support 
several ISDNInCallsBehavior features, enter a summation 
of the individual feature values. For example, to support 
both [2048] and [65536] features, set ISDNInCallsBehavior 
= 67584 (i.e., 2048 + 65536). 
[ISDNInCallsBehavior_x]  Same as the description for the parameter 
ISDNInCallsBehavior, but per trunk (i.e., where x denotes the 
Trunk ID). 
Q.931 Layer Response Behavior

isdn-bits-ns-behavior 
[ISDNIBehavior] 
Bit-field used to determine several behavior options that 
influence the behaviour of the Q.931 protocol.  
  [0] = Disable (default). 
  [1] NO STATUS ON UNKNOWN IE = Q.931 Status 
message isn't sent if Q.931 received message contains an 
unknown/unrecognized IE. By default, the Status message 
is sent.  
Note: This value is applicable only to ISDN variants in 
which sending of Status message is optional. 
  [2] NO STATUS ON INV OP IE = Q.931 Status message 
isn't sent if an optional IE with invalid content is received. 
By default, the Status message is sent.  
Note: This option is applicable only to ISDN variants in 
which sending of Status message is optional. 
  [4] ACCEPT UNKNOWN FAC IE = Accepts 
unknown/unrecognized Facility IE. Otherwise, the Q.931 
message that contains the unknown Facility IE is rejected
