S1-7 and S1-8: Line Build Out (Models 3088/K and 3088/T)

Switches S1-7 and S1-8 define the shape of the waveform on the T1 or E1 line, as shown in
S1-7

Note
75 Ohms corresponds to the BNC connectors on Model 3088/K.
120 Ohms corresponds to the T1/E1 (RJ-45) interface on Models 3088/K
and 3088/T.

S2-2 Line Code (Models 3088/K and 3088/T)

Switch S2-2 defines the T1 or E1 network line coding.

S2-3: Annex A/B (Models 3088/K and 3088/T)

Annex A is typically used in North American-like networks, whereas Annex B is typically used in European-
like networks. The different annexes specify different PSD (power spectral density) masks because of the differ-
ence in T1 and E1 PSDs.

S2-4 through S2-5: Clock Mode (Models 3088/K and 3088/T))

The RocketLink-G can operate in one of three clock modes: internal, network, or receive-recover.

Clock Mode
The on-board oscillator in the 3088 provides clock for both T1/E1
and DSL lines.
3088 uses the RX clock from the T1/E1 interface as the clock for
the DSL link.
3088 uses the RX clock from the DSL interface as the clock for the
T1/E1 line.
