E1 Link Card
The E1 link card (V168708) provides an aggregate connection using a framed or unframed 2.048 MHz E1
link. The card provides both an RJ45 connector interface and dual BNC Rx/TX interface. Use the one
appropriate to your network equipment.
NOTE: The E1 link card can only be fitted to a V100 revision D4 or later, or to a revision D3 unit
modified to MR68700D3 or later.
NOTE: ISDN signalling is not supported on the aggregate link.
On the V100 motherboard, JP21 – JP23 and JP25 & JP27 need to be set to the E1 position rather than the
ISDN position:
a. JP21, JP22, JP23 - Fit links in position 1-2 for E1, closest to the left hand side of the board viewed from
the rear, (2-3 are default for TDM/ISDN)
b. JP25, JP27 - Fit links in position 1-2 for E1, farthest from the rear of the board viewed from the rear
(2-3 are default for TDM/ISDN)
