|
| gsmCsCustomerIdentifier |
.1.3.6.1.4.1.562.2.4.1.127.103.1.1 |
|
This attribute holds the Customer Identifier (CID).
Every component has a CID. If a component has a cid attribute, the
component's CID is the provisioned value of that attribute;
otherwise the component inherits the CID of its parent. The top-
level component has a CID of 0.
Every operator session also has a CID, which is the CID
provisioned for the operator's user ID. An operator will see only the
stream data for components having a matching CID. Also, the
operator will be allowed to issue commands for only those
components which have a matching CID.
An operator CID of 0 is used to identify the Network Manager
(referred to as 'NetMan' in DPN). This CID matches the CID of
any component. Values 1 to 8191 inclusive (equivalent to 'basic
CIDs' in DPN) may be assigned to specific customers.

|
| gsmCsV42T400DetectTimer |
.1.3.6.1.4.1.562.2.4.1.127.5.10.1.1 |
|
This attribute specifies the maximum amount of time that the IWF
waits for an Originator Detection Pattern (ODP) or Answerer
Detection Pattern (ADP). ODP/ADP is a series of special bit
patterns used during the call setup procedures.
If the IWF is the Originator of the call, it starts sending ODP
patterns and waits for an ADP for the duration of T400 milliseconds
from the answerer at call setup time.
If the IWF is the Answerer of the call, it waits for an ODP for T400
seconds from the originator and if it receives during that time it
sends an ADP pattern to the originator at the call setup time. Since
both sides operate with different values of T400 timer, a higher
value increases the chance of a successful call setup.
Changes to this attribute do not effect existing calls.
|
| gsmCsV42T401AckTimer |
.1.3.6.1.4.1.562.2.4.1.127.5.10.1.2 |
|
This attribute specifies the maximum amount of time that the IWF
waits for an acknowledgment before retransmitting a frame. Since
information about the T401 timer is not carried in the Exchange
Identification (XID) negotiations at call setup time, both sides
operate with different timer values. The value for T401 depends on
many factors, such as propagation delay or frame processing time.
A frame is retransmitted up to N400 times if the timer T401 expires
before an acknowledgment for a frame is actually received. The
performance of the data link layer can be impacted by the value of
this timer as retransmissions of frames occur on expiry of timer
T401.
Changes to this attribute do not effect existing calls.
|
| gsmCsV42T402AckDelayTimer |
.1.3.6.1.4.1.562.2.4.1.127.5.10.1.3 |
|
This attribute specifies the maximum amount of time that the IWF
may wait following the receipt of any frame requiring a reply before
it initiates transmission of an appropriate reply in order to ensure
that the reply frame is received by the remote error-correcting entity
prior to expiration of the T401 timer of the remote error-correcting
entity. Since information about the T402 timer is not carried in the
Exchange Identification (XID) negotiations at call setup, both sides
operate with different timer values. If this timer expires, then the
reply that would have been returned prior to its expiration is not
sent. The performance of the data link layer can be impacted by the
value of this timer as retransmissions of frames occur on expiry of
timer T401. For better performance, a value of t402AckDelayTimer
(T402) equal to half the value of t401AckTimer (T401) is
recommended.
Changes to this attribute do not effect existing calls.
|
| gsmCsV42T403IdleProbeTimer |
.1.3.6.1.4.1.562.2.4.1.127.5.10.1.4 |
|
This attribute specifies the maximum amount of time that the IWF
allows to elapse without frames being exchanged. The link is
permitted to remain idle with no frames being exchanged on the
data link. Upon expiry of this timer, the IWF polls its peer for
status. Since information about the T403 timer is not carried in the
Exchange Identification (XID) negotiations at call setup time, both
sides operate with different timer values.
Changes to this attribute do not effect existing calls.
|
| gsmCsV42TxN401FrameSize |
.1.3.6.1.4.1.562.2.4.1.127.5.10.1.5 |
|
This attribute specifies the maximum number of octets that can be
carried in the information field of an Information (I) frame,
Exchange Identification (XID) frame, and a Unnumbered
Information (UI) frame from the IWF to the remote entity. The
default value is 128 octets, and no XID negotiations required for
txN401FrameSize. If the value for txN401FrameSize value is set to
other than 128 octets, then XID frames are exchanged to negotiate a
value. The value provided for txN401FrameSize sets up the bounds
during XID negotiations. The IWF performs XID negotiations with
this value as a minimum or maximum value. If a value greater than
128 is specified, then the IWF negotiates or attempts to negotiate a
value between the 128 (as a minimum) and the given value (as a
maximum). If a value less than 128 is specified, then the IWF
attempts to negotiate a value between the given value (as a
minimum) and 128 (as a maximum). Any value can be specified as
long as it is within the provisionable limits. However, a value equal
to or close to 128 is recommended.
The negotiated value can be viewed in the component
GsmIwfV42Op attribute txN401FrameSize. Changes to this attribute
do not effect existing calls.

carried in the information field of an Information (I) frame,
Exchange Identification (XID) frame, and a Unnumbered
Information (UI) frame from the remote entity to the IWF. The
default value is 128 octets, and no XID negotiations are required for
rxN401FrameSize. If the value set for rxN401FrameSize is other
than 128, XID frames are exchanged to negotiate a value. The value
provided for rxN401FrameSize sets up the bounds during XID
negotiations. The IWF performs XID negotiations with this value as
a minimum or maximum value. If a value greater than 128 is
specified, then the IWF attempts to negotiate for a value between
128 (as a minimum) and the given value (as a maximum). If a value
less than 128 value is specified, then the IWF attempts to negotiate
for a value between the given value (as a minimum) and 128 (as a
maximum). Any value can be specified as long as it is within the
provisionable limits. However, a value equal to or close to the
default is recommended.
The negotiated value can be viewed in the component
GsmIwfV42Op attribute rxN401FrameSize. Changes to this attribute
do not effect existing calls.

unacknowledged sequenced Information (I) frames from the IWF to
the remote entity. The default value is 15 frames, and if this value is
used then no Exchange Identification (XID) negotiations are
required for txKwindowSize. If the value set for txKwindowSize is
other than 15, then XID frames are exchanged to negotiate a value.
The value provided for txKwindowSize sets up the bounds during
XID negotiations. The IWF performs XID negotiations with this
value as a minimum or maximum value. If a value greater than 15 is
specified, then the IWF attempts to negotiate a value between 15 (as
a minimum) and the given value (as a maximum). If a value less
than 15 is specified, then the IWF attempts to negotiate for a value
between the given value (as a minimum) and 15 (as a maximum).
Any value can be specified as long at it is within the provisionable
limits. However, a value equal to or close to the default is
recommended.
The negotiated value can be viewed in the component
GsmIwfV42Op attribute txKwindowSize. Changes to this attribute do
not effect existing calls.
|
| gsmCsV42RxKwindowSize |
.1.3.6.1.4.1.562.2.4.1.127.5.10.1.8 |
|
This attribute specifies the maximum number of outstanding
unacknowledged sequenced Information (I) frames from the remote
entity to the IWF. The default value is 15 frames, and if this value is
used then no Exchange Identification (XID) negotiations are
required for rxKwindowSize. If the value set for rxKwindowSize is
other than 15, then XID frames are exchanged to negotiate a value.
The value provided for rxKwindowSize sets up the bounds during
XID negotiations. The IWF performs XID negotiations with this
value as a minimum or maximum value. If a value greater than 15 is
specified, then the IWF attempts to negotiate a value between 15 (as
a minimum) and the given value (as a maximum). If a value less
than 15 is specified, then the IWF attempts to negotiate for a value
between the given value (as a minimum) and 15 (as a maximum).
Any value can be specified as long as it is within the provisionable
limits. However, a value equal to or close to the default is
recommended.
The negotiated value can be viewed in the component
GsmIwfV42Op attribute rxKwindowSize. Changes to this attribute

.1.3.6.1.4.1.562.2.4.1.127.6.1.1.4 |
|
This variable represents the storage type value for the
gsmCsV42bis tables.
|
| gsmCsV42bisCompressionDirection |
.1.3.6.1.4.1.562.2.4.1.127.6.10.1.1 |
|
This attribute specifies the V.42bis data compression direction to be
supported. The value for compression direction is negotiated at link
setup by the data link protocol by way of the Exchange
Identification (XID) negotiation of parameter P0 (compression
direction).
During XID negotiation of parameter P0, both sides (IWF and
mobile or IWF and Public Switched Telephone Network (PSTN))
agree on the compression direction.
Valid values are:
none, No compression is present.
encode, The data sent by the IWF to the other entity is compressed.
decode, The data received by the IWF from the other entity is
compressed.
both, The data sent and received by the IWF is compressed.
The negotiated value can be viewed in the component
GsmIwfV42bisOp attribute compressionDirection. Changes to this
attribute do not effect existing calls.
|
| gsmCsV42bisMaximumCodewords |
.1.3.6.1.4.1.562.2.4.1.127.6.10.1.2 |
|
This attribute specifies the maximum number of V.42bis codewords
the IWF supports. A codeword is a binary number that represents a
string of characters in compressed form. V.42bis keeps a dictionary
of codewords for each compression direction. During Exchange
Identification (XID) negotiation of parameter P1 (number of
codewords), both sides (IWF and mobile or IWF and Public
Switched Telephone Network (PSTN)) agree on the total number of
codewords in the dictionaries. Changes to this attribute impact the
compression ratio for the encoder (component GsmV42BisOp
attribute compRatioEncoder). Changes also impact the amount of
memory used (more memory is used when increasing the attribute).
The gain in performance obtained from the selection of a larger
dictionary may be offset by the larger codeword size needed, and
for certain types of data, better performance may be obtained by
using a smaller dictionary.
The negotiated value can be viewed in the component
GsmIwfV42bisOp attribute maximumCodewords . Changes to this
attribute do not effect existing calls.

|
This attribute specifies the maximum number of characters allowed
in a string represented by a codeword that the IWF supports. Each
codeword in a V.42bis dictionary represents a string of characters.
During Exchange Identification (XID) negotiation of parameter P2
(maximum string size), both sides (IWF and mobile or IWF and
Public Switched Telephone Network (PSTN)) agree on the
maximum string length to be used in the dictionaries. Changes to
this attribute impact the compression ratio for the encoder
(component GsmIwfV42bisOp attribute compRatioEncoder).
The negotiated value can be viewed in the component
GsmIwfV42bisOp attribute maximumStringSize. Changes to this
attribute do not effect existing calls.
|
| gsmCsV42bisActionOnError |
.1.3.6.1.4.1.562.2.4.1.127.6.10.1.4 |
|
This attribute specifies whether or not V.42bis takes down the call
or resets the link when any of the following errors occur:
1.Receipt of STEPUP (step up codeword size) codeword when it
would cause C2 (current code word size) to exceed N1 (maximum
code word size).
2. Receipt of a codeword, at any time, equal to C1 (next empty
dictionary entry).
3. Receipt of a codeword representing an empty dictionary entry.
4. Receipt of a reserved command code.
5. Receipt of any other error.
If the value is resetLink, the error corrected connection and V.42bis
dictionaries are reset. Some data is lost but the call continues. If the
value is takeDownCall, the call is taken down.
Changes to this attribute do not effect existing calls.

|
This attribute indicates what percentage (0 to 100%) of a given
LogicalProcessor has been reserved for the data calls which are
currently active. When the assignedCapacity reaches 100%, no new

of a call, the compute requirements will vary. The compute capacity
required for a given call type depends on the type of call established
including such factors as connection type, data compression, user
rate, error correction, flow control; therefore, at call establishment
the compute capacity is added to the assignedCapacity for a
LogicalProcessor. When the call is released, it's compute capacity
is subtracted from the assigned capacity for the Lp.The
GsmIwfCallServer uses this information to balance the distribution
of data calls across the logical processors.
