# T-FRAP Network Port

#### Circuit Identifier

#### Clock Source

#### Density

#### Framing

#### Interface

#### Line Build out

#### Line Coding

#### 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
