4. The extended setting range for the E&M-4W-8P card is from -16.3 to +7.5 dB.
5. The default coding is a-inv for E1 and u-law for T1.
Choosing a Rate other than 64K allows you to select an ADPCM slot.
STATE
The State setting determines whether the port is active or inactive. An inactive port does not
occupy a time slot on a WAN link. Set this field to stdby (standby) for ports that will not be
used or that are not yet configured. Or, set it to actv (active) for ports that are ready for use.
WAN/SRV
The WAN/SRV setting identifies the WAN link or server card assigned to this port. If you
choose wan, you also must select the desired port (w1-1 through w4-2) of a WAN card for
transmission over a T1 or E1 link. Or, choose serv to assign the card port to a server card in
the system. This can be an ATM or FRS card, which resides in chassis slot P1, P2, or P3. You
must then choose a logical port on that card. The user option is not used.
It is not necessary to assign all ports of the same E&M card to the same WAN link or server
card, or to contiguous time slots on a WAN link.
TS
The TS setting identifies the time slot on the WAN link to which this port is assigned. This
value is from 1 to 24 for T1 links and 1 to 31 for E1 links. However, time slot 16 is not
available for E1 links that are programmed for CAS or CCS signaling. For a display of
available time slots, refer to the cross-connect map for the WAN link selected.
MODE
The Mode setting specifies whether or not a port uses E&M signaling, or if it operates in the
Transmission-Only (TO) mode. Use the to mode if you are connecting the port to a four-wire,
dedicated-line modem that does not require E&M signaling. The signaling type for all eight
ports of an E&M card is defined by setting hardware switches S1 through S4 as described
earlier in this chapter. Select e&m for standard Type I, II, IV, or V signaling. Select e&mR2
for symmetrical R2 signaling for calls originating from either the digital or analog side. The
R2mod setting provides modified R2 signaling for Motorola paging terminal equipment.
