1.2 Configure the E1 Ports
The E1 Configuration Switches for both Port 1 and Port 2 are on the component side of the UIM-2E1 circuit
board, opposite the faceplate/label. When facing the Configuration Switches, Port 1 switches are on the
left and Port 2 switches are on the right. Switches for both ports are numbered from left to right, #1-8.
1.2.1 Frame Type
Frame type is the data encapsulation method. An E1 frame consists of 248 data bits (an 8-bit
sample of each of the 31 E1 data channels), plus 8 synchronization bits, transmitted at a rate of
8,000 frames per second across the E1 line.

AUTION
Net to Net Technologies strongly recommends the use of proper electrostatic discharge (ESD) precautions when handling
this equipment.
N
OTE
Port 2 Configuration Switches on the UIM-2E1 are NOT USED: frame type and line code for Port 2 are determined by
the Port 1 switch settings. BOTH ports determine speed and timing configurations via communication with the remote
E1 equipment to which the UIM-2E1 is connected.
