Model 3088A Series User Manual 2 • Configuration
Table 2 lists the Model 3088A’s configurable parameters.
Table 2. OnSite configurable parameters
Parameter Description Possible Values
Password The password used to login to the console. 1-10 characters
Circuit ID The circuit ID used to identify the unit. 1-64 characters
DTE Loops
(model /CA & /A) The DB-25 interface can request LALs and RDLs using its RRDL and
RLAL pins. If DTE loops are disabled, requests for loopbacks on
these pins will be ignored. Enabled or Disabled
TX Clock
(models /CA, /A &
/D) Defines where (RS-232, V.35 or X.21) serial transmit data is sam-
pled in relation to the TX clock: on the falling edge (normal) or the
rising edge (inverted) of the TX clock. Normal or Inverted
DSL Data Rate/
Timeslots Defines the number of DSL timeslots. The DSL data rate is calculated
by the equation: data rate = DSL timeslots x 64k. This value also
defines the maximum serial/E1 data rate. 1–72
Serial/E1 Timeslots Defines the total number of serial/E1 timeslots utilized. This value
must be less than or equal to DSL timeslots.
3–89 (RS-232)
3–89 (V.35)
3–89 (X.21)
1–32 (E1)
Timeslot
Mapping
(Model /K) Defines E1–to–DSL timeslot mapping. By default defined/utilized DSL
timeslots are mapped to the first n data–bearing timeslots on the E1
line. Line type determines which timeslots are data–bearing:
E1–Unframed: 0–31
E1–Fractional: 1–31
E1–CRC: 1–31
E1–MF: 1–15,17–31
E1–CRCMF: 1–15,17–31
Line Type
(Model /K) Defines the framing format of the E1 line. E1–Unframed
(Clear Channel
G.703)
E1–Fractional
E1–CRC
E1–Multiframe
E1–CRC & Multiframe
Line Code
(Model /K) Selects line coding for the E1 line. AMI
HDB3 (E1 only)
Line Build Out
(Model /K) Selects wave form used on the E1 line. Pulse–75 Ohm(E1)
Pulse–120 Ohm (E1)
RX Equalizer
(Model /K) When enabled, this feature removes signal distortion introduced on
the E1 cable. Enabled (select for
long–haul link).
Disabled (select for
short–haul link). Long
haul LBO (line build-
out) is defined by
ANSI T1.403).
Pass Framing
(Model /K) When enabled, the OnSite transparently passes framing information
(E1 TS0) over the DSL link to the remote E1 network. Enabled or Disabled.
