Network Mode


Clock Source

Enter the clock source for the T1 network. It can either be supplied by the network line, an internal crystal, or from the network (DTE source).
Range: Internal, Network, or DTE
 
Note: In a point-to-point application, make certain one of the units is configured for Network timing and the other for Internal timing. In a point-to-network application, make certain the unit is configured for Network timing.
 

Network Mode

Defines the type of service provided on the attached network line.
Range: Dedicated (CBO) or Frame Relay (HDLC)
 

Interface

This field defines the network interface.
Range: DSX-1 (disables CSU functions for line driver or external CSU applications. Drive distances up to 6000 feet (0 -- 1,829 m), or CSU (enables CSU functions such as Line Build-out, density monitoring, and certain diagnostic features. Drive distances up to 655 feet (0 -- 177m)
 

Circuit Identifier

Enter the carrier-supplied alpha-numeric T1 circuit identifier.
Range: 0 ~ 30 alphanumeric characters
 

Framing

This field defines the network framing type.
Range: D4 (standard super frame format), ESF-54016 (AT&T style ESF), or ESF-ANSI (ANSI style ESF)
 

Line Coding

This field defines the network Bi-Polar encoding scheme type.
Range: AMI (Alternate Mark inversion. No line coding density protection), or B8ZS (Binary 8 Zero Suppression. Line coding density protection supplied. Density monitoring should be set to None)
 

Density

This field defines the maximum number of consecutive ones that can be transmitted to the network. This setting is not applicable if Interface type is configured for DSX-1.
Range: None (density monitoring is disabled. This setting should be used if Line Coding is configured for B8ZS or DTE Port Density is configured for Bit-7 Stuffing, 1:8 (at least 24 ones in each 192-bit sliding group is set to a 1), 1:16 (at least a single one in each 16-bit sliding group is set to 1), 1:64 (at least a singe one in each 64-bit sliding group is set to a 1)
 

Line Build out

Line Build Out (LBO) type. Regulates the transmitted dB line-level strength. Normally set according to the network carrier requirements.
Range: 0, -7.5 dB, or -15 dB
