Refer to Interface Cabling to Station Message Detail Recording (SMDR) Output 
Device on page 9-63 for c onnection information.
The 475 or 572 printers can be used as an output receiving device for station 
message detail recording (SMDR). The recommended option settings for these 
printers are shown in the following tables. Also, a TELESEER, station message 
detail recording (SMDR), 94A Local Storage Unit (LSU), or Customer Premises 
Equipment (CPE) can be used as the output receiving device. Administration

Audio Information Exchange (AUDIX)
Interface Option Settings for G3i 
Systems
AUDIX is sometimes connected to the switch through the processor interface 
circuit pack. The first circuit on the processor interface can be connected directly 
to the AUDIX through the PROCESSOR INTERFACE connector on the rear of 
the control carrier. Any of the remaining three circuits on the processor interface 
to be used to support AUDIX must b e connected through a modular processor 
data module (MPDM) serving as the interface link for AUDIX. The option settings 
recommended for the modular processor data module (MPDM) in this 
application are shown in Table H-26.
TN760 Tie Trunk Circuit Pack Option 
Settings
The TN760 circuit pack interfaces between four 6-wire tie trunks and the time 
division multiplex (TDM) b us. Two tip and ring pairs form a 4-wire analog 
transmission line. An E and M pair is used for signaling. The E and M pair are 
direct current signaling leads used for call setup. The E lead receives signals 
from the tie trunk and the M lead transmits signals to the tie trunk. 
To choose the preferred signaling format (Table H-30 and Table H-31), set 
switches on the TN760 circuit pack and administer the port per Figure H-2 and 
Table H-29. Table H-26. Option Switch Settings on Modular Processor Data

TN464C, D, E, F Option Settings
The TN464 circuit pack interfaces between a 24 or 32 channel Central Office 
(CO)/Integrated Services  Digital  Network (ISDN) or tie trunk and the Time 
Division Multiplex (TDM) bus. 
The TN464C and TN464D act as Digital Service Level 1 (DS1)/E1 interfaces and 
Integrated Services  Digital  Network (ISDN) Primary Rate Interface (PRI) 
interfaces and have the following attributes:
n1,544-meg a bits p er second (Mb ps) Digital Service Level 1 (DS1) (24 
channel integrated services digital network (ISDN)) and 2.048 me gabits 
per second Mb ps) E1 (32-channel Integrated Services Digital Network 
(ISDN)) transmission rates
nAdministrable A-law companding and Mu-law companding 
nCyclical redundancy checking (CRC) 4 check
nStratum 3 clock compatibility
nD-channel connectivity for Integrated Services  Digital  Network (ISDN) 
primary rate interface (PRI)
The TN464D is a superset of the TN464C and has the following a d ditional 
attributes: supports digital release link tie trunks and MFC, R2 Direct Inward 
Dialed (DID) signaling. In addition to supporting tie trunk, Central Office (CO) 
trunk, and Direct Inward Dialed (DID) trunk protocols, the TN464D supports 
bit-oriente d signaling protocols and bit-oriented Direct Inward Dialed (DID) 
signaling protocols. 
The TN464C and TN464D have the following signal leads: LBACK2, LBACK1, 
LO, LO (out), LI, LI (in to Private Branch Exchange (PBX)).
TN464C/D Option Settings
To choose the bit rate and the line impedance match, set plugs (TN464 C & D) 
on the c ircuit pack. Insert the jumper b locks into the p ins to join the center row of 
pins and the row designating the desired options. 
Set the impedance and bit rate as follows:
