TTLNA

NIU/DSX panel – Location where telco drops T-1s to local facility

Input/Output Unit (IOU) – Physical termination of T1s.

Universal Radio Controller (URC) – Electrical Termination of up to 8 T1s. Contains the LIU and MC,Overall control of the NodeB, Line Interface Unit (LIU) – Performs CSU functions, Routing of information to/fm T1 and UMTS Channel Unit Cards. Master Controller (MC) – Overall control of the BTS, routes user traffic and OAM signaling to/fm RNC

UMTS Channel Unit 64 (UCU64) – Performs coding and decoding of user traffic. Also used for Overhead channels.

Multi-Carrier Radio (MCR) – 15 Mhz radio used to modulate and demodulate user traffic on/off RF carrier. Performs RX diversity, CLGC, Ant Tests, and EDPD

P2PAM – Power Amplifier used to amplify TX signal to it final power level. 40W max power output, can be lower based on site design.

Dual Diversity Duplex Filters – Provides filtering of the TX and RX signals. Powers TTLNAs.
