To afford some protection and increase reliability to a PRI/T1/E1 digital trunk
facility, the network interface of the digital trunk card should not connect directly
to the network. The LTU or CSU is generally required for connections to the
public network, and is strongly recommended for private network facilities as well.
Typically, the LTU/CSU is a small, wall or rack mounted box. The LTU/CSU is
Customer Premises Equipment (CPE) in most countries and is available from several
different manufacturers.
See Coral Service and Peripheral Cards Installation Manual , Chapter 3 - Digital
Trunks

Figure 7-14 describes the connection between the BATTipx and the LTU/CSU.
5 LTU/CSU Connection
The LTU/CSU terminal block is dedicated to the LTU/CSU, only. Do not connect any
ancillary equipment to this connection, it could cause catastrophic failure to the
PS500 AC power supply. Unauthorized use of the LTU/CSU terminal block will void the
warranty from the manufacturer for the entire installation, and it is viewed as an illegal
modification of FCC registered equipment.
The LTU/CSU terminal block is designed to support the LTU/CSU unit, only.
