Timeslots Versus Bandwidth

1.7 TIMESLOTS VERSUS BANDWIDTH

Each fiber pair supports 12 timeslots, or up to 75 MHz of bandwidth. Table 1-2 shows

the maximum bandwidth versus the number of timeslots.

If more than 70 MHz is required per Remote, up to three additional fiber pairs can be

brought to the Remote to get up to up to 280MHz per Remote (or 300MHz if all four

are GSM-1800). This supports applications where there are two Classic DARTs or

Single SuperDARTs or one Dual SuperDART in a Remote RF Module.

The SeRF (Serialized RF) digital protocol consists of digitized RF, 100BASE-T Ethernet,

and Host to Remote communication and management. The protocol provides you

with full access to the 100BASE-T Ethernet connection between the Host and each

Remote, and the ability to provision the RF spectrum of the DARTs. The digitized RF

portion of the SeRF protocol is divided into 12 timeslots, with each timeslot

representing roughly 5 MHz of digitized RF spectrum. Utilizing the full 12 timeslots

yields between 60 and 80 MHz of total digitized RF on each SeRF SFP laser connection.
