35.8 The ADMP file system interface subsystem, known as
FIOS, provides an interface for the application tasks running on
the ADMP-C processor to perform input and output operations
on the disk subsystem. It receives the input/output requests from
the application task, transforms them into file control transaction
blocks, and relays them to...

Data Call-Processing 
Software35.13 Call processing and switching refers to the setting up and
tearing down of packet-switched data calls. This does not
include voice or other circuit-switched data call setups. These
calls may be any combination of X.25 end-point, asynchronous
packet assembler/disassembler calls, and/or connections to or
from the administrative ports built into the ADMP card. (These
administrative ports are known as pseudo packet device
handlers.) Call-processing software...

UI (User Interface) function of the ADMP is designed
to perform menu presentation conventions for the other
applications. It is the job of the UI to present menus to the user,
screen and check data entered by users, perform security
checking, and transmit...

TL-130500-1001Loader35.23 The Loa x is responsible for initializing and loading any
data system 
de,;lce which requires code and/or tables. The
loader accesses the disk through 
FIOS to read code or data
records and transmits them to the device being loaded. Once a
device is loaded, the success or failure of the load is reported to
the ERMA event handler.
CHANDLER35.24 The CHANDLER (CEC Handler) is an ADMP function
(CEC Handler)which is solely responsible for dealing with requests from the
CEC. The CEC...

TL-130500-I 001Transmission36.0 This section provides information on trunk transmission
And Loss Plansand loss plans as they apply to the system. The VNLP (Via Net
Loss Plan) and the FLP (Fixed Loss Plan) are described and
trunk loss objectives and digital pad switching rules are given.
All trunks on a system should be designed for either VNLP or
FLP and must conform to certain trunk loss constraints.
The 
OMNI SI is a time-divided pulse-code-modulated system
that can be operated as main, tandem, or...

TL-130500-1001
When a Tie trunk is switched to a CO trunk that has less than 2dB of loss, the PABX can be programmed to switch in a 2 dBpad to ensure good balance. A pad should not be provided
when the CO trunk ICL (Inserted Connection Loss) exceeds 2 
dB.
Because pad control is part of the data base, the fact that the
PABXCO facility is short (less than 2 dB) should be noted when
ordering a PABX.
The ICL objectives for the VNL plan are given in Table 36.1.
These are established network objectives and...

The FLP was developed specifically for systems where a direct
digital interface to a digital trunk facility is provided. A direct
digital trunk interface eliminates the toll terminating equipment
(pads, four-wire terminating sets, and voice frequency
repeaters) that is normally adjusted to provide the proper ICL on
the receive transmission path of a PABX. A method of providing
the required loss to the PABX was required and switchable pads
provided the most reasonable solution....
