DXC-4 E1/T1 Grooming Device

DXC-4 is a standalone unit used for grooming T1 / E1 digital transmission lines. DXC-4 can groom DS0 timeslots including the signaling information, into a single T1 / E1 link towards a central location. It can also groom traffic from up to 8 fractional T1 / E1  links into a single T1 / E1 uplink.

Status and diagnostic information is defined, configured, and monitored using one of the following methods:
Serial connection using a local terminal
Ethernet connection using SNMP and RADview, RADís client-server, or CORBA-based Network Management System
Web browser
Inband, using a dedicated timeslot over the T1 / E1 uplink (for remote units).

The T1 interface complies with AT&T TR-62411, ANSI T1.403 and AT&T Pub. 54016. The T1 interface supports D4 and ESF framing  formats. Zero suppression over the line is selectable for either transparent, B7ZS or B8ZS. The user-selectable integral CSU ensures  a range of up to 2.1 km (1.3 miles.) T1 links have a 100Ω balanced interface

The E1 interface meets ITU recommendations G.703, G.704, G.706, and G.732. It supports either 2 or 16 frames per multiframe, with  or without CRC-4. Line coding is HDB3 or AMI. The user-selectable integral LTU ensures a range of up to 2 km/1.2 miles. The E1  uplink interface is switch-selectable for a 120Ω balanced interface, or 75Ω unbalanced interface.

Scalable design allows the unit to be ordered with 4 or 8 ports, to support 4 or 8 link channels.

DXC-4 can operate in the following timing modes:
Internal: The internal oscillator of DXC-4 provides clock signals to the T1 / E1 uplink and link channels
Station: The unit uses a station clock from its station input as the transmit clock for the uplink and link channels. It can also transmit the station clock to another DXC-4 device. The station clock rate is 2.048 Mbps for E1 links and 1.544 Mbps for T1 links.
External (LBT): Clocking is taken from one of the received clocks from the uplink or from any of the link channels
Automatic: DXC-4 checks the link channels for synchronization and uses the receive clock of the first synchronized channel.

Diagnostic capabilities include local and remote loopbacks on the T1 / E1 uplink and link channels.

The device has a combined AC/DC power supply with optional redundancy.

DXC-4 is a compact standalone unit. One or two units can be installed side-by-side in a 19-inch rack using an optional rack mount 
adapter kit.
