When in TDM or MCMP mode, the selections are 1, 2,
3, 4, 5, 6, or Aggr. Aggr is the communications interface
between the aggregate data path (on the TDM or MCMP
circuit card) and the DSU. In Bridge mode, the selections
are 1, 2, 3, 4, 5, 6, or DCE. DCE is the communications
interface between Port 1 (on the TDM or MCMP circuit
card) and the DSU; Port 1 is the aggregate link to the
DTE, while Ports 2 through 6 may be connected to
DBM-Vs, DBM-Ss, or DBM-Ds.

External Leads
Through the External Leads (ExtL) selection, you can
display the state of four general-purpose leads on the
EIA-232-D/V.24 Port 1 interface: Pins 12 and 13 for
output (control leads) and Pins 19 and 23 for input (alarm
leads). If the configuration option External Leads (Ext
Leads) is set to ExtLd, you can change the state of the two
output leads from the DCP or from a 6700 or 6800 Series
NMS. If the DSU’s diagnostic protocol is ADp and the
CCN by External Leads (CCN by EL) configuration
option has been enabled, a control DSU reports any
changes to the four leads to the 6700 or
6800 Series NMS as part of its health and status poll
response.
