Link Type —The input/output protocol for encapsulation and SAR to AALS
conversion.
DXI— ATM DXI Mode 1A
HDLC/SDLC —HDLC/SDLC frame pass-through
Frame Relay —Frame Relay Interworking (Frame Relay Forum Specification 5
and 8; modes 1 and 2).
DCE/DTE Mode (HSIM only)—The type of cable connected to the port: DCE or
DTE. This parameter is configurable for HSIMs only. The QSIM Port Configuration
menu displays the Cable Type as a read-only parameter derived automatically from
the type of cable connected to the module.
LBO (DS1 FAM only)—Line Build Out. LBO refers to the signal
generation/regeneration of the distance between the PathBuilder S700 and the
next crossconnect of FOTs (Fiber Optic Terminal system), in feet:
1-100 , 100-200 ,
200-300 , 300-400 , 400-500 or 500-600 .
Gain Limit (DS1 FAM only) — Setting for the receive signal level: 26 or 36 dB .
Line Code (DS1 FAM only)—The zero code suppression technique configured to
the FAM port. Set this parameter to match the service provider or device
connection line coding. The default is
B8ZS . The Line Code must match at local
and remote ports.
Framing (DS1 FAM only)—The type of frame organization configured for the T1
port interface: D4 or ESF . Set this parameter to match the service provider or
device connection framing.
TDM Mode — n x 56k or n x 64k (clear channel), depending on the attached
equipment.
Timing (DS1 FAM only) — The type of input clock service configured for the DS1
FAM module. Set the timing source to system if you are using the DS1 FAM
module to connect to the network.
