7. H4R CAPACITY GUIDELINES
The ADTRAN T200 H4R is designed for installation in a prewired Type 200 or Type 400 enclosure. Capacity
guidelines for deployment are provided in Table 5.
8. MAINTENANCE
The ADTRAN T200 H4R requires no routine maintenance for normal operation. In case of equipment malfunc-
tion, perform an in-band loopback from the Central Office. If a malfunction is confirmed, replace the unit.
The ADTRAN T200 H4R has looping capability through the channel allowing digital loopback in fault isolation.
The loopback is activated remotely. The type of loopbacks the H4R supports will be dependent upon the loopback
capabilities of the transceiver units utilized on the circuit. Refer to the Installation and Maintenance Practice of the
specific H4TU-C or H4TU-R for a list of loopback codes.
Performance monitoring, diagnostics, and loopbacks are also available from the craft interface at the
H4TU-C or H4TU-R.
ADTRAN does not recommend that repairs be attempted in the field. Repair services may be obtained by returning
the defective unit to ADTRAN. Refer to “Appendix A, Warranty” for further information.
