APPN Transmission Group Characteristics
APPN TG Characteristics are used by the APPN network when choosing a route from one
node to another. The route selection criteria are defined in the Class of Service (COS)
definitions. There are five standard COSs: #BATCH, #BATCHSC (BATCH Secure), #INTER,
#INTERSC (INTER Secure), and BLANK. Some important things to consider about how a
COS uses the TG Characteristics are:
#BATCH considers all Effective Capacities of 56K and above to be the same, unless the Cost/
Connect or Cost/Byte is not zero, in which case Effective Capacities of 19.2K and above are
considered to be the same. For example, if a 16Mbit token ring line uses an APPN TG with
the Cost/Connect is set to 10, then that line will be considered the same as a 19.2Kb SDLC
line with a Cost/Connect of 00.
#INTER considers all Effective Capacities of 4M and above the same, unless the Cost/Connect
or the Cost/Byte are not zero, in which case 56K and above are considered the same.
Neither of the secure COSs will use a line that has the Security set as Nonsecure.
None of the Default COSs use the User-Def fields. To use these, new COSs must be defined
that assign weight ranges to the User-Def fields.
#BATCH does not use the Propagation Delay field, but for #INTER it’s very important. For
example, if #INTER is used, and the Propagation Delay is not set to LAN, then all of the LAN
speeds will be downgraded to 56Kb or lower.
Effective Capacity
This field toggles to specify the band width in Bits/Second of the line using this Link Profile.
Possible values are Minimum, 1.2K, 2.4K, 4.8K, 7.2K, 9.6K, 14.4K, 19.2K, 38,4K, 48K,
56K, 57.6K, 64K, 128K, 256K, 512K, 1M, 2M, 4M, 8M, 10M, 16M, and Maximum.
4M is the default for Frame Relay. Frame relay users should ensure that the Effective Capacity
matches their line speed.
Propagation Delay
This field toggles to Minimum, LAN, Telephone, Pktswtnet (packet switched), Satellite, and
Maximum.
LAN is the default for Frame Relay. Frame relay users should ensure that the Propagation
Delay is appropriate for their Frame Relay line.
Cost/Connect
This data entry field specifies Cost per connection in the range of 0-255.
Cost/Byte
This data entry field specifies Cost per byte in the range of 0-255.
